Summary: Solution combustion route derived perovskite type barium nickelate (BaNiO3) nanoparticles showed high electrocatalytic activity for overall water splitting, with over-potentials of 253 mV for OER and 427 mV for HER, achieving a current density of 10 mAcm(-2) in 1.0 M KOH. When used as a bifunctional electrocatalyst in a two-electrode alkaline electrolyser, the BaNiO3 nanoparticles enabled benchmark current density at a low cell voltage of 1.82 V. Remarkably, the electrocatalytic performance of the setup improved by 4.9% after continuous overall water splitting for 24 h at 30 mAcm(-2). Thus, BaNiO3 nanoparticles can serve as a cost-effective alternative for noble metal electrocatalysts in clean H-2 production.

Summary: Efficient and economic bifunctional electrocatalyst for water splitting to produce hydrogen is urgently required. Layered double hydroxides (LDHs) are effective for oxygen evolution reaction (OER) but show challenging hydrogen evolution reaction (HER) activity. A hydrothermal-treatment strategy enhances the HER and OER performance of NiCo-LDH by creating metal vacancies and forming Ni/Co(OH)2 phase, tuning electronic structure, and improving electrical conductivity. The resulting NiCo-LDH-OH catalyst exhibits significantly reduced overpotentials for both HER and OER, and demonstrates superior activity for overall water splitting with no decay after 20 hours. This work paves a new path for efficient LDHs-based HER/OER bifunctional catalysts.

Summary: A high-performance ORR/OER hybrid catalyst is designed by hybridizing a hierarchically porous atomically dispersed FeN2 catalyst with uniform Co3O4 nanoparticles. The catalyst exhibits superior bifunctional activity towards the ORR and OER, with a half-wave potential of 0.886 V and an overpotential of 0.227 V at 10 mA cm(-2) in 0.1 M KOH. The resulting Zn-air batteries show ultrahigh peak power density of 236 mW cm(-2) and a long discharge-charge cycle of over 165 h at 5 mA cm(-2). Density functional theory calculations reveal that the FeN2 active sites significantly improve the ORR and OER catalytic activities. These results indicate that the hybrid catalyst effectively enhances the performance of zinc-air batteries for practical application.

Summary: To address the issues of Ni-rich NCM, Al (CF3SO3)(3) was proposed as a solid electrolyte additive to regulate the CEI in single-crystalline NCM811. The facile oxidation of CF3SO3- and subsequent reactions with reactive species from NCM811 and electrolyte lead to the formation of a robust sandwich CEI film containing sulfur and aluminum species. This CEI film not only prevents electrolyte decomposition but also alleviates the formation of inactive rock-salt phase on NCM811 surface, resulting in a high-capacity retention of 91.5% after 200 cycles under 0.5 C.

Summary: Properly engineered heterojunction photocatalysts can effectively separate photoexcited electron-hole pairs and improve the photocatalytic hydrogen evolution performance. In this study, 3D bicontinuous nanoporous reduced graphene oxide (np-rGO) was used as a supporting matrix for CdS nanoparticles to achieve a highly efficient photocatalysis system for hydrogen production. The bicontinuous internal ligament and open nanopores in the 3D nanoporous heterojunction contribute to improved light absorption and utilization capacity. The construction of a p-n heterojunction with staggered band alignment in CdS/np-rGO accelerates the transport of photo-excited carriers, leading to a significant increase in hydrogen generation rate.

Summary: Ternary intermetallic electrides (LaTMSi) are a class of electride materials with unique geometric and electronic structures, showing excellent catalytic performance. The structural stability of LaTMSi in air and water is higher compared to conventional electrides. However, their catalytic activities decrease in the presence of H2O as the product. High-temperature calcination can remove the deactivated surface caused by exposure to H2O, but frequent reactions with H2O and calcination can lead to complete phase transition to oxides. The dissociation of H2O and phase transition are also observed in LaCoSi and LaNiSi ternary intermetallic electrides.
