Tripping the light fantastic: Despite small band gap energies (1.7–1.8 eV), BaZrO3-BaTaO2N 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 H2 and O2 was also demonstrated using a photoelectrochemical cell consisting of a BaZrO3–BaTaO2N solid solution as an anode and a Pt wire cathode.
