Summary: In this paper, the stability, adsorption configuration, and activated electronic properties of CO2 on different surfaces (C2N, M/C2N, M2/C2N) were investigated using DFT. The results showed that NiCo/C2N exhibited the highest stability and good CO2 adsorption properties. Additionally, the study explored the generation of C1 products from CO2 reduction and C-C coupling reactions on M/C2N and M2/C2N materials. It was found that the outermost electron distribution and density of states of the transition metals influenced the pathways for C1 generation from CO2 reduction on different surfaces, and NiCo/C2N was favorable for CO2 reduction reactions.

Summary: In this study, the eNRR performance of 30 single metal atoms supported on a C2N monolayer (M@C2N) was evaluated using density functional theory calculations and the computational hydrogen electrode model. A new thermodynamically stable Pd-W hetero-metal diatomic catalyst supported on the C2N monolayer (PdW@C2N) was also designed. The results showed that PdW@C2N exhibited excellent performance in catalyzing the eNRR process, with low overpotential, ultra-low NH3 desorption free energy, and high selectivity towards eNRR over hydrogen evolution reaction (HER). Compared to its monomer and homonuclear diatom counterparts, PdW@C2N showed superior eNRR performance. The revealed mechanism suggested that the preferential H adsorption over N-2 on the active site may not hinder the eNRR process, especially in heteronuclear diatom catalysts.

Summary: The structural parameters, dynamic stability, electronic, and optical properties of Zn1-xCdxTe, Zn1-xHgxTe, and Cd1-xHgxTe ternary alloys were systematically studied. These ternary alloys were found to be dynamically stable. Direct electronic transitions were allowed at the Gamma point for all compounds. The band gap energy showed a drastic decrease from ZnTe to HgTe. By alloy engineering, the band gap energy could be varied in a wide range of 0-2 eV. Several novel compounds exhibited suitable band gaps (1.3-1.6 eV) and good carrier mobility for potential optoelectronic applications. Optical properties were compared in the visible region, and an improvement in the absorption coefficient was observed for Zn0.75Hg0.25Te and Cd0.75Hg0.25Te. This study will contribute to the discovery of desired materials with low toxicity and high efficiency for solar cells.

Summary: This study presents a new design of van der Waals heterogeneous single-atom catalysts (vdW-SACs) for electrocatalytic nitrogen reduction reaction (eNRR). Large-scale density functional theory (DFT) calculations were employed to investigate the stability, NRR activity, and selectivity of these vdW-SACs. It was found that the W-C3/P-C3 catalyst exhibits the highest activity with the lowest overpotential due to the asymmetric active sites and the pd hybridization between W 5d orbitals and N2 π* antibonding orbitals. This research provides new insights for the development of advanced electrocatalysts for NRR and beyond.

Summary: Single-atom catalysts (SACs) are considered as the ultimate route to improve metal utilization efficiency. In this study, Pt SACs with Pt-C2N and Pt-N-2 configurations were synthesized by regulating the N vacancy level of ultrathin g-C3N4 (UCN). The distinctive configuration of Pt-C2N and Pt-N-2 was confirmed through X-ray absorption fine spectroscopy. Pt-C2N exhibited a higher H-2 evolution performance (112.5 mu mol h(-1)) compared to Pt-N-2 (78.6 mu mol h(-1)). Density functional theory (DFT) calculations revealed that Pt atoms tend to absorb on C-2C and construct strong metal-support interactions.
