Achieving highly performant photoanodes for oxygen evolution is key to developing photoelectrochemical devices for solar water splitting. In this work, BiVO4 photoanodes are enhanced with a series of core–shell structured bimetallic nickel‐cobalt phosphides (MPs), and key insights into the role of co‐catalysts are provided. The best BiVO4/Ni1.5Co0.5P and BiVO4/Ni0.5Co1.5P photoanodes achieve a 3.5‐fold...
Rechargeable aqueous zinc–ion batteries are regarded as promising energy storage devices due to their attractive economic benefits and extraordinary electrochemical performance. However, the sluggish Zn2+ mass transfer behavior and water‐induced parasitic reactions that occurred on the anode–electrode interface inevitably restrain their applications. Herein, inspired by the selective permeability...
The application of halide perovskites in the photoelectrochemical generation of solar fuels and feedstocks is hindered by the instability of perovskites in aqueous electrolytes and the use of expensive electrode and catalyst materials, particularly in photoanodes driving kinetically slow water oxidation. Here, solely earth‐abundant materials are incorporated to fabricate a CsPbBr3‐based photoanode...
Gas transport in the porous electrode plays a crucial role in the performance of fuel cells. Inthis work, gas convection caused by temperature gradient, typically ignored in the analysis of gastransport in fuel cells, has been evaluated quantitatively. The correlation of gas convection with gas pressure and electrode thickness is investigated systematically. In addition, limiting current density loss...
