The year of 2018

2018.8.7 Congratulations to Dr. Xianghong Niu for his paper entitled "Photo-Oxidative Degradation and Protection Mechanism of Black Phosphorus: Insights From Ultrafast Dynamics" being published in The Journal of Physical Chemistry Letters (J. Phys. Chem. Lett. 2018, DOI: 10.1021/acs.jpclett.8b02060). Highlight: In this work, we carry out time-domain ab initio nonadiabatic molecular dynamics to understand the photogenerated electron dynamics at the molecules/BP interfaces. It is found that oxygen can trap the photogenerated electrons of BP rapidly owing to strong electron-phonon (e-p) coupling and becomes active superoxide under light illumination. This study provides the first in-depth understanding of BP degradation and protection mechanism from excited state dynamics and can be applicable to other 2D photo-oxidative degradation.

2018.7.19 Congratulations to Bing Wang for his paper entitled "High Curie-Temperature Intrinsic Ferromagnetism and Hole Doping-Induced Half-Metallicity in Two-Dimensional Scandium Chlorine Monolayer" being published in Nanoscale Horizons (Nanoscale Horiz. 2018,DOI: 10.1039/C8NH00101D). Highlight: Herein through comprehensive first-principles calculations and Monte Carlo simulation, we predict a promising 2D scandium chlorine (ScCl) monolayer with intrinsic ferromagnetism and a Curie temperature of 185 K. Moreover, a small amount of hole doping can induce a transition from a ferromagnetic metal to a half-metal. These intriguing electronic and magnetic properties make the ScCl monolayer a promising candidate for spintronic applications.

2018.7.13 Congratulations to Qisheng Wu for his paper entitled "Transition Metal Dihydride Monolayers: A New Family of Two-Dimensional Ferromagnetic Materials with Intrinsic Room-Temperature Half-Metallicity" being published in The Journal of Physical Chemistry Letters (J. Phys. Chem. Lett. 2018, 9, 4260-4266). Highlight: Two-dimensional (2D) ferromagnetic materials with intrinsic half-metallicity are highly desirable for nanoscale spintronic applications. Here, we predict a new and stable family of 2D transition-metal dihydride (MH2; M = Sc, Ti, V, Cr, Fe, Co, Ni) monolayers with novel properties. In particular, the CoH2 monolayer is a perfect half-metal with a wide spin gap of 3.48 eV and an above-room-temperature Curie point (339 K). The new family of MH2 monolayers are promising functional materials for spintronic applications due to their novel magnetic properties.

2018.7.9 Congratulations to Chongyi Lingfor his paper entitled "Single Molybdenum Atom Anchored on N-Doped Carbon as a Promising Electrocatalyst for Nitrogen Reduction into Ammonia at Ambient Conditions" being published in Journal of Physical Chemistry C (. J. Phys. Chem. C 2018, 122, 16842-16847). Highlight: The synthesis of NH3 at ambient conditions remains a coveted goal for chemists. We study the potential of the newly synthesized single-atom catalysts, i.e., single metal atoms (Cu, Pd, Pt, and Mo) supported on N-doped carbon for N2 reduction reaction (NRR) by employing first-principles calculations. Our study offers new opportunities for advancing electrochemical conversion of N2 into NH3 at ambient conditions.

2018.5.1 Congratulations to Qisheng Wu for his paper entitled "Two-Dimensional AuMX2 (M=Al, Ga, In; X=S, Se) Monolayers Featuring Intracrystalline Aurophilic Interactions with Novel Electronic and Optical Properties" being published in ACS Applied Materials & Interfaces(ACS Appl. Mater. Interfaces 2018, 10, 16739–16746). Highlight: In this work, we show that aurophilicity can serve as an engineering approach to expand the structural dimensionality for nanomaterials design. Specifically, we predict a series of stable two-dimensional (2D) AuMX2 (M = Al, Ga, In; X = S, Se) structures featuring intracrystalline aurophilic interactions, which render AuMX2 monolayers a potentially new series of 2D materials that are of fundamental importance in gold chemistry and of technological importance for nanoelectronics.

2018.4.25 Congratulations toYilv Guo for her paper entitled "Half-metallicity and enhanced ferromagnetism in Li-adsorbed ultrathin chromium triiodide" being published in Journal of Materials Chemistry C (J. Mater. Chem. C. 2018, 6, 5716-5720). Highlight: Herein, based on first-principles calculations, we show that the CrI3 monolayer can be switched from semiconducting to half-metallicity by lithium atom adsorption. Moreover, the adsorption of Li atoms can further enhance the ferromagnetism of CrI3 sheets by increasing both the magnetic moment and the Curie temperature. The robust half-metallicity together with improved ferromagnetism may open up new promising applications of CrI3-based materials in spintronics.

2018.4.18 Congratulations to Dr.YInghe Zhao for his paper entitled "Surface Vacancy-Induced Switchable Electric Polarization and Enhanced Ferromagnetism in Monolayer Metal Trihalides" being published in Nano Letters (Nano Lett. 2018, 18, 2943-2949). Highlight: Atom-thick 2D materials with switchable electric polarization are now urgently needed for their rarity and important roles in nanoelectronics. We unveil that surface I vacancies not only enhance the intrinsic ferromagnetism of monolayer CrI3 but also induce switchable electric polarization. This work opens up a new and general way toward pursuing low-dimensional multifunctional nanodevices.

2018.1.17 Congratulations to Dr. Qiang Li for his paper entitled "On-surface synthesis: a promising strategy toward the encapsulation of air unstable ultra-thin 2D materials" being published in Nanoscale (Nanoscale 2018, 10, 3799-3804 ). Highlight: Herein, the on-surface growth of an oxidation-resistant 2D thin film of a metal coordination polymer is demonstrated by multiscale simulations. Our facile strategy for enhancing the environmental stability of ultrathin materials is expected to accelerate efforts to implement 2D materials in electronic and optoelectronic applications.

2018.1.11 Congratulations to Bing Wang for his paper entitled "Ultrathin Semiconducting Bi2Te2S and Bi2Te2Se with High Electron Mobilities" being published in The Journal of Physical Chemistry Letters (J. Phys. Chem. Lett. 201, 9, 487-490). Highlight: Two ultrathin two-dimensional (2D) semiconductors, namely, Bi2Te2S and Bi2Te2Se nanosheets are predicted to own moderate band gaps (~0.7 eV) and high electron mobilities (∼20 000 cm2/Vs), and they can absorb sunlight efficiently through the whole incident solar spectrum. The exceptional properties render Bi2Te2X (X = S, Se) monolayers promising candidates in future high-speed (opto)electronic devices.

2018.1.1 Congratulations toYixin Ouyang for his paper entitled "Molybdenum sulfide clusters immobilized on defective graphene: a stable catalyst for the hydrogen evolution reaction" being published in Journal of Materials Chemistry A (J.

The year of 2017

2017.11.21 Congratulations to Xianghong Niu for his paper entitled "Arsenene-Based Heterostructures: Highly Efficient Bifunctional Materials for Photovoltaics and Photocatalytics" being published in ACS Applied Materials & Interfaces (ACS Appl. Mater. & Interfaces 2017, 9, 42856-42861). Highlight: On the basis of accurate band structure calculations by combining the many-body perturbation GW method with an extrapolation technique, we demonstrate that arsenene-based heterostructures paired with molybdenum disulfide, tetracyano-quinodimethane, or tetracyanonaphtho-quinodimethane can form type II band alignments. These arsenene-based heterostructures cannot only satisfy all the requirements as photocatalysts for photocatalytic water splitting but can also show an excellent power conversion efficiency of ∼20% as potential photovoltaics.

2017.10.9 Congratulations to Dr. Qionghua Zhou for his paper entitled "Band-edge engineering via molecule intercalation: a new strategy to improve stability of few-layer black phosphorus" being published in Physical Chemistry Chemical Physics (Phys. Chem. Chem. Phys. 2017, 19, 29232-29236). Highlight: Our first-principles calculations demonstrate that enlarging the interlayer spacing can effectively shift the conduction band minimum down to suppress the generation of superoxide and the enlargement can be achieved by intercalating small molecules like H2 and He into BP. Moreover, the molecule intercalated BP maintains high hole mobility, which makes it a better two-dimensional semiconductor for practical applications.

2017.9.23 Congratulations to Yinghe Zhao for his paper entitled "Exploitation of the Large‐Area Basal Plane of MoS2 and Preparation of Bifunctional Catalysts through On‐Surface Self‐Assembly" being published in Advanced Science (Adv. Sci. 2017, 4, 1700356). Highlight: In this work, on‐surface self‐assembly is demonstrated to be an effective, facile, and damage‐free method to take full advantage of the large ratio surface of MoS2 for HER by using multiscale simulations, which opens up a new and promising avenue (on‐surface self‐assembly) toward the full exploitation of the basal plane of MoS2 for HER and the preparation of bifunctional catalysts for overall water splitting.

Phys. Chem. Lett. 2017, 8, 4368). Highlight: This study provides a profound understanding of the degradation mechanism of InSe via in-air oxidation and opens a possible route to stabilize InSe against ambient. We expect that this detailed study also provides ideas for the universal degradation problem existing in 2D materials.

2017.8.22 Congratulations to Qisheng Wu for his paper entitled "Au6S2 monolayer sheets: metallic and semiconducting polymorphs" being published in Materials Horizons (Mater.

Int. Ed. 2017, 129, 9259-9263). Highlight: To date, it is generally accepted that BP degrades in air via light‐induced oxidation. Herein, we report a new degradation channel via water‐catalyzed oxidation of BP in the dark. This new degradation mechanism lays important foundation for the development of proper protecting schemes in black phosphorus‐based devices.
