Carbon nitride (CN x ) is a light‐absorber with excellent performance in photocatalytic suspension systems, but the activity of CN x photoelectrodes has remained low. Here, cyanamide‐functionalized CN x (NCNCN x ) was co‐deposited with ITO nanoparticles on a 1.8 Å thick alumina‐coated FTO electrode. Transient absorption spectroscopy and impedance measurements support that ITO acts as a conductive binder and improves electron extraction from the NCNCN x , whilst the alumina underlayer reduces recombination losses between the ITO and the FTO glass. The Al2O3|ITO : NCNCN x film displays a benchmark performance for CN x ‐based photoanodes with an onset of −0.4 V vs a reversible hydrogen electrode (RHE), and 1.4±0.2 mA cm−2 at 1.23 V vs RHE during AM1.5G irradiation for the selective oxidation of 4‐methylbenzyl alcohol. This assembly strategy will improve the exploration of CN x in fundamental and applied photoelectrochemical (PEC) studies.
