Tripping the light fantastic : Despite small band gap energies (1.7–1.8 eV), BaZrO 3 ‐BaTaO 2 N solid solutions (Zr/Ta≤0.1) are capable of photocatalyzing both water oxidation and reduction even under irradiation above 660 nm. Solar water splitting to form H 2 and O 2 was also demonstrated using a photoelectrochemical cell consisting of a BaZrO 3 –BaTaO 2 N solid solution as an anode and a Pt wire cathode.
