a) Light chopped LSV (scan rate=10 mV s−1, anodic direction) and b) CPPE at +0.3 V vs. RHE of LTCA|TiO2 photocathodes modified with NiP, no co‐catalyst or Pt (* indicates where irradiation was temporarily interrupted in CPPE) c) H2 quantification for LTCA|TiO2|NiP from (b). The dashed line represents the theoretical amount of H2 based on the charge passed (i.e., 100 % Faradaic yield). Conditions: Aqueous Na2SO4 (0.1 m) at pH 3 electrolyte solution under simulated solar irradiation (AM1.5G) and a constant Ar purge.
