The fabrication of particle-based photoelectrodes by coating or dipping procedures-similar to the scaled fabrication of battery electrodes-can be a route to overcome the efficiency-cost tradeoff of photoelectrochemical (PEC) water splitting devices. Additi ...
Recently in Joule, Zhang, Li, and colleagues reported a new benchmark in photocatalytic overall water splitting. By optimizing the co-catalysts and redox mediator between the light absorbers in a two-step heterogeneous photosystem, the authors reached an a ...
Concurrent solar generation of hydrogen and CO through photoelectrochemical (PEC) water and CO2 electrolysis, and the subsequent use of the product gas mixture in conventional Fischer-Tropsch processes, has the potential to provide a flexible pathway for d ...

Oxysulfoselenide semiconductor photocatalysts absorb light at longer wavelengths than the corresponding oxysulfides. However, the synthesis of oxysulfoselenides is challenging due to excessive particle growth and the limited availability of metal selenide ...
Nanostructured metal oxide semiconductors have shown outstanding performances in photoelectrochemical (PEC) water splitting, but limitations in light harvesting and charge collection have necessitated further advances in photo-electrode design. Herein, we ...
Hydrogen is a highly versatile fuel that may become one of the key solutions to face our future energy challenges. Among all these methods for hydrogen production, solar water splitting offers possible advantages regarding components integration, stability ...
