Splitting Water by Electrochemistry and Artificial Photosynthesis: Excellent Science but a Nightmare of Translation?

Abstract Water splitting to its elements, either by electrochemistry or by solar light, is among the most covered areas in nanostructured functional materials. This personal account article analyzes potential downstream translation problems and reviews alternative chemistries with a potential higher return. Liberation of oxygen for accepting the holes is a kinetically demanding half reaction afflicted with kinetic hindrances and high overpotentials, while at the same time no marketable value is created (atmospheric oxygen is free to use). In spite of exciting science created, application in real industrial set‐ups is currently impossible, and possible funding promises to contribute to a sustainable society become a debt difficult to return. We discuss possible alternative targets of (photo)electrochemistry as entry points where chemical value products and technical oxidants are created, with partially greater ease, lower losses, and higher benefits.
