A capillary photoelectrochemical (PEC) system is developed using cellulose‐nanofiber (CNF)‐templated TiO 2 nanostructures to perform water splitting reactions outside of the electrolyte body, where the electrolyte is supplied through capillary force‐driven nano/micro‐channels in the CNF film. Enhanced reaction kinetics and higher efficiencies are observed in the capillary PEC process compared with conventional in‐electrolyte PEC setups.
