Summary: This study reports a method of synthesizing ultrafine bimetal PtMo nanocrystals through an anchoring-sites engineering strategy, in which N-rich carbon can provide abundant anchoring sites and suppress over-aggregation. The PtMo-NC catalyst exhibits superior HER performance in both alkaline and acidic conditions, delivering smaller overpotentials (80 mV and 63 mV) at a current density of 100 mA cm(-2). The introduction of Mo atoms into Pt can reduce the energy barrier of water molecule dissociation and optimize the absorption strength of H intermediates on Pt sites, thereby boosting the catalytic HER performance. This study offers a universal strategy for designing ultrafine nanocatalysts for high-efficiency electrocatalysis.

Summary: This study systematically investigates the role of transition metal-functionalized N-doped carbon nanosheets as multifunctional electrocatalyst supports for hydrogen evolution/oxidation reactions in alkaline media. The results show that all the M-N-C nanosheets, except Cu-N-C and Ag-N-C, can promote the alkaline HER/HOR electrocatalytic activity of Pt, with Mn playing a more significant role. The promotion effect of the M-N-C support is closely associated with the electronegativity of the metal dopants and the filling degree of their d-orbitals.

Summary: Developing highly efficient and durable hydrogen evolution reaction (HER) electrocatalysts is crucial. MoSe2 is a promising candidate for HER catalysis but suffers from stacking layers and low conductivity. This work presents a novel approach by incorporating diethylene glycol solvent into the interlayers of MoSe2 during synthesis, which transforms into graphene (Gr) upon thermal treatment. The resulting MoSe2-Gr composite exhibits significantly enhanced HER activity and long-term stability, surpassing the state-of-the-art Pt/C catalyst.

Summary: This paper investigates the effect of halogen atoms doping on the type and height of graphene/MoSe2 Schottky using density functional theory. The results show that halogen doping can effectively change the type and height of the Schottky junction. F, Cl, and Br doping changes the Schottky type from n-type contacts to ohmic contacts, while I and At doping reduce the Schottky barrier height. These findings are significant for achieving lower Schottky barrier heights in logic devices.

Summary: Electroreduction of CO2 into valuable fuels and chemicals is a promising solution to energy and environmental issues. This study introduces an interface-enhanced strategy by depositing nitrogen-doped graphene on a copper foam surface, resulting in increased selectivity towards ethanol production. Experimental and theoretical results suggest that the graphene coating serves as a fast charge transport channel and provides confined nanospace for mass transfer, while the nitrogen doping promotes the interaction between nitrogen and CO2 and enhances the coupling pathways for C-C formation. The interface effect of the Cu-N-G catalyst stabilizes intermediates and promotes ethanol formation. This interface-enhanced strategy offers insights for the design of copper-based electrocatalysts for CO2RR towards multi-carbon products.

Summary: Based on first-principles density functional theory, this study investigated the structural and electronic properties, as well as the hydrogen evolution reaction (HER) activity, of heterostructures composed of different MXene and N-doped graphene (NDG). The results showed significant electron transfer at the interfaces of the heterostructure, and the addition of MXene modified the electronic structure of the NDG surface. Furthermore, the heterostructure enhanced the adsorption of H on the NDG surface and improved HER activity. The effects of heterostructure types and H coverage rate on HER activity were also investigated. This study suggests that appropriately designed MXene/NDG heterostructures have the potential to be HER catalysts.
