Summary: Hybrid catalysts consisting of metal nanoparticles on a metal oxide support have been shown to improve oxygen evolution reaction and hydrogen evolution reaction activity through an in situ exsolution process. The generation of oxygen and cation vacancies in the oxide support during exsolution can decrease charge-transfer energy, facilitating charge transfer between metal nanoparticles and the oxide support. These findings establish a structure-property relationship in complex hybrid catalysts for efficient water splitting and suggest a new strategy for designing various hybrid catalysts for electrochemical reactions.

Summary: TiO2/CuO composites were prepared via a two-step method. The results of X-ray diffraction and transmission electron microscopy showed the substitution of Cu2+ for Ti4+ in the TiO2 lattice and the presence of Cu2+ species in the CuO lattice. Scanning electron microscopy revealed a morphology change in the sample and the formation of an interface between TiO2 and CuO. X-ray photoelectron spectroscopy and Raman spectra indicated the presence of oxygen vacancies (VO) and Ti3+ in the lattice. UV-vis absorption spectra demonstrated a widening of the absorption range and a decrease in the bandgap with increasing amount of CuO. Additionally, the composites exhibited room-temperature ferromagnetism (RTFM) related to VO and the exchange interaction between Ti3+ and Ti4+ at the interface.

Summary: We systematically investigated the optical and magnetic properties of Ru-doped hybrid improper perovskite Ca3Mn2O7. Ru doping enhanced the ferromagnetism of Ca3Mn2O7 and quasi-2D antiferromagnetic fluctuation effect was observed in certain doped samples. The optical bandgaps of the doped samples were reduced and distortion of the Mn-O bonds was observed. The Ru-doped materials with the coexistence of ferromagnetic and antiferromagnetic orderings are expected to be excellent candidates for magnetoelectric devices.

Summary: Regulating the energy barrier of *COOH is crucial for the rate determining step in the photocatalytic reduction of CO2 to produce CO gas. In this study, an appropriate Zn vacancy on ZnIn2S4 was synthesized to enhance the photocatalytic CO2 reduction capacity (CO: 5.63 mmol g(-1) h(-1)) and selectivity (CO: 97.9%). Different sulfhydryl groups were used to regulate the formation of Zn vacancies in ZnIn2S4, leading to the generation of unsaturated sulfur coordination state adjacent to the Zn vacancy with fewer electrons compared to ZnIn2S4 without Zn vacancy. Experimental analysis and theoretical calculations demonstrated that the appropriate Zn vacancy shifted the Gibbs free energy of *COOH from endothermic to exothermic during the photoreduction of CO2. This work provides an engineering method to optimize cation vacancies and improve the efficiency of photocatalytic CO2 reduction by adjusting the energy barrier of intermediates.

Summary: The discovery of metals as catalytic centers for nitrogen reduction reactions (NRR) has led to interest in single-atom catalysts (SACs). However, existing SACs have poor activity and low selectivity, which falls short of industrial requirements. Through first principles screening, doping engineering can effectively regulate the NRR performance of beta-Sb monolayer. Among 24 transition metal dopants, Re@Sb shows the best NRR catalytic performance with low limiting potential and can inhibit hydrogen evolution reaction (HER) while achieving a high theoretical Faradaic efficiency of 100%. These findings accelerate catalyst discovery for ammonia synthesis and contribute to understanding structure-performance correlations.

Summary: In this study, a facile strategy of anion engineering was proposed to improve the bifunctionality of layered LiCoO2 (LCO) for Zn-air batteries (ZABs). Partial substitution of fluorine for oxygen induced oxygen vacancies and modulated the electronic structure of Co, thereby accelerating oxygen electrocatalysis kinetics. The potential gap (Delta E) between the OER potential and ORR potential of LiCoO1.8F0.2 (LCOF0.2) catalyst (0.986 V) was significantly lower than that of pristine LCO catalyst (1.162 V), indicating a higher bifunctional activity. The ZABs using LCOF0.2 as the air electrode exhibited a peak power density of 193 mW cm-2, which was 1.53-fold higher than that of the LCO-based ZABs. This study demonstrates the feasibility of F doping to improve the bifunctional electrocatalytic performance of LiCoO2.
