Summary: A collaborative interface optimization strategy was used to prepare a metal-organic framework (MOF) derived heterostructure electrocatalyst (MXene@RuCo NPs), which showed excellent performance in electrocatalytic hydrogen/oxygen evolution reactions. The electrocatalyst exhibited low overpotentials and high current densities, thanks to the introduction of second active sites and the enhancement of the number of active sites by doped Ru. The heterogeneous interfaces of MXene/RuCo NPs in the catalysts also played a significant role in improving the charge transfer rate and reducing the energy barrier of the catalytic reaction.

Summary: In this study, nanosized Co9Se8 and TiO2 particles were fabricated using a hydrothermal process, followed by the construction of various Co9Se8/TiO2 heterojunctions using a physical solvent evaporation strategy. The photocatalytic H2 evolution experiment demonstrated that the H2 evolution rate over 15%-Co9Se8/TiO2 reached 8282.7 μmol∙g-1∙h-1 under 300 W Xe lamp irradiation, using 20% triethanolamine (TEOA) as the sacrifice agent. This rate was 29.9-fold and 95.8-fold higher than that of pristine TiO2 and Co9Se8, respectively. The enhanced photocatalytic performance was attributed to improved light absorption ability and the formation of S-scheme heterojunctions, which promoted the separation and migration of photo-induced charges.

Summary: Researchers prepared Mn-doped nickel cobalt phosphide (Mn-NiCoP) with nanopins arrays on nickel foam, which exhibited low overpotentials of 148 mV for HER and 266 mV for OER at a high current density. The water splitting performance of Mn-NiCoP as both anode and cathode was 1.69 V and maintained 94% efficiency after 240 hours. By conducting first-principles calculations, it was determined that the synergistic effect of moderate Mn doping and Co alloying contributed to the improvement of both OER and HER performance on Mn-NiCoP. This study provides inspiration for optimizing the OER performance of traditional HER catalysts, facilitating overall water splitting using a single catalyst in the same solution.
