Liquid-Metal-Induced Hydrogen Insertion in Photoelectrodes for Enhanced Photoelectrochemical Water Oxidation

Abstract: Fast charge separation and transfer (CST) is essential for achieving efficient solar conversion processes. This CST process requires not only a strong driving force but also a sufficient charge carrier concentration, which is not easily achievable with traditional methods. Herein, we report a rapid hydrogenation method enabled by gallium-based liquid metals (GBLMs) to modify the prototypical WO3 photoelectrode to enhance the CST for a PEC process. Protons in solution are controllably embedded into the WO3 phot… Show more

“…Ga-based liquid metal can also serve as liquid-phase reducing agents . Wang et al make use of the reducing feature of Ga, realizing the insertion of hydrogen into the lattice of WO 3 photoanodes (H x -WO 3 ) (Figure c) . As a result, the charge carrier concentration of H-WO 3 is increased, which facilitates the charge separation and transfer process and thus enhances the photoelectrochemical water oxidation.…”
