p‐Type InP Nanopillar Photocathodes for Efficient Solar‐Driven Hydrogen Production

Perfect texture: The roles of surface nanotexturing, TiO2 passivation, and a ruthenium cocatalyst on the photoelectrochemical evolution of hydrogen by using p-InP photocathodes are investigated. Higher current densities and more favorable onset potentials are observed after surface nanotexturing. NHE=normal hydrogen electrode.
