Summary: This study systematically investigated the electrocatalytic activity of M2B2, M3B4, and M4B6 type MBenes for multifunctional HER, OER, and ORR through first-principles calculations. Ni2B2 and Co3B4 MBenes were found to be promising multifunctional HER/OER/ORR electrocatalysts, while Fe3B4 MBene was expected to be a promising bifunctional electrocatalyst for HER/ORR. The study also established new scaling relations between the adsorption energies of OOH* and O* on MBenes, providing a new approach for the rational design of MBene-based electrocatalysts.

Summary: In this study, a facile approach for decorating atomically dispersed Pt cocatalysts on CdS nanorods is reported. The PtSA+C/CdS photocatalysts exhibit optimized photocatalytic hydrogen evolution activity, achieving a reaction rate 1.6- and 7.3-fold higher than Pt-SA/CdS and Pt-NP/CdS photocatalysts, respectively. The synergy between single-atom and atomic cluster active sites is responsible for the enhanced photocatalytic activity.

Summary: Pt-Ag nanoalloys show remarkable chemical order depending on their size and composition. Recently, a reversed size-dependent stabilization of ordered nanophases was observed around equiconcentration. In this study, we investigate the composition-dependent chemical ordering in Pt-Ag nanoalloys, revealing a strong Ag segregation on the surface at low silver content and an L1(1) ordered phase in the core at higher silver concentrations, interrupted by a concentric multishell structure in a narrow range of compositions.

Summary: A novel pincer complex-bridged porphyrin polymer synthesized in this study exhibits excellent electrocatalytic hydrogen evolution reaction (HER) performance and potential for fabricating photoelectrochemical (PEC) cells. The experimental and theoretical studies suggest that the Cu/Ru heterobimetallic centers in the polymer enhance electron transfer and regulate electronic properties, boosting (photo)electrocatalytic activity for HER. This strategy provides a new approach to fabricate porphyrin-based polymers for effective HER (photo)electrocatalysis.

Summary: In this study, inter-doped tungsten-ruthenium oxide heterostructures were proposed to enhance the activity and stability of acidic oxygen evolution reaction (OER) in proton-exchange membrane water electrolyzers (PEMWE). The introduction of high-valent W species induced the oscillation of Ru sites during OER and maintained the continuous operation of the active sites. The asymmetric Ru-O-W active units generated around the heterostructure interface enhanced the intrinsic OER activity.

Summary: This work proposes a novel method to design a heterogeneous CoP/CoO electrocatalyst on mesopore nanobox carbon/carbon nanotube (CoP/CoO@MNC-CNT) that enriched active sites and synergistic effect. The well-defined heterointerfaces could lower the energy barrier for intermediate species adsorption and promote OER and ORR electrochemical performances. The ZABs-based CoP/CoO@MNC-CNT air-cathode shows high performance in terms of ORR half-wave potential and OER overpotential, and the flexible ZABs exhibit highly mechanical stability, demonstrating their application potential in wearable electronic devices.

Summary: Sodium (Na) metal anodes are potential candidates for high-energy density and high-power density batteries, but the dendrite growth of Na metal limits their practical applications. Oxygen-rich functional groups can be introduced into carbon fiber cloth to achieve superwettability, providing a wettable matrix to retain liquid Na-K alloy and achieve stable cycling. This concept of enthalpy-driven wettability regulation can be applied to the design of host materials for other liquid metals and alloys.

Summary: In this study, a noncoplanar antiferromagnetic phase was experimentally obtained in the antiperovskite system Mn3Sn0.5Zn0.5Cx through neutron powder diffraction analysis. This phase exhibits zero thermal expansion behavior in a wide temperature range from 10 to 162 K. The zero thermal expansion in this noncoplanar antiferromagnetic ordered system is attributed to the competition between nearest antiferromagnetic direct exchange and ferromagnetic superexchange interaction.
