Tunable ambipolar photoelectrochemical behavior emerges from microdomains of nanostructured p‐type CuFeO 2 and n‐type Fe 2 O 3 that arise from a single facile solution‐processed thin film. The switchable operation of this system is controlled by chemical, optical, or electronic inputs with a uniquely high photocurrent response (on the order of 1 mA cm –2 ), suitable for robust practical application as an oxygen photoregulator.
