Solar‐Driven Co‐Production of Hydrogen and Value‐Add Conductive Polyaniline Polymer (Adv. Funct. Mater. 52/2022)

Solar-Driven Hydrogen Production In article number 2204807, W. Y. Ho-Baillie, Hongjun Chen, and co-workers report a solar-driven hydrogen production with a 98.6% faradaic efficiency and 33% power savings compared to conventional water-splitting without the use of ion-selective membranes. The process produces a high-value by-product, a conductive polymer, with a 96% yield. For demonstration, a perovskite solar cell and lowcost earth-abundant CoP catalyst are utilized successfully.
