X. D. Wang, Z. Cai, and co‐workers demonstrate on page 2262 a cellulose‐nanofiber (CNF)‐enabled capillary photo‐electrochemical (PEC) photoanode for performing water‐splitting reactions outside of the electrolyte body, mimicking the water‐transmission process in plants. Driven by the capillary force, the electrolyte transmits through the nano‐/microchannels in the CNF film and reaches the photocatalyst sites. Enhanced reaction kinetics and higher efficiency can be achieved by the capillary PEC process.
