A range of transition-metal oxynitrides and a nitride were examined as potential photocatalysts active under visible light. (Oxy)nitrides based on tantalum, niobium and titanium are found to absorb visible light (λ ≤ 600 nm), and some of them are found to evolve H₂ or O₂ from aqueous solutions containing a sacrificial electron donor (CH₃OH) or acceptor (Ag⁺), respectively, via band gap excitation without noticeable photo-degradation of the catalyst itself.
