With a view to developing a photoanode for visible light‐driven water oxidation in solar water splitting cells, pure‐monoclinic WO 3 nanorod crystals with N 2 intercalated into the lattice were synthesized by using hydrazine with a dual functional role—as an N atom source for the in situ N 2 intercalation and as a structure‐directing agent for the nanorod architecture—to gain higher incident photon‐to‐current conversion efficiency at 420 nm than with most previously reported WO 3 electrodes.
