摘要：
Cu2ZnSnS4(CZTS) thin film photocatalytic water splitting for hydrogen production under visible light irradiation has been reported together with CZTS nanoparticles prepared by ultrasonic spray pyrolysis and hydrothermal method, respectively. CZTS thin film provided higher H(2)production rate (68.68 mu mol g(-1) h(-1)), which was 32 times higher than that of CZTS nanoparticles (2.08 mu mol g(-1) h(-1)) without loading any noble metals. What's more, photocatalytic activity of CZTS thin film remained 94% after 48 h which confirmed the good stability and reusability of CZTS thin film. CZTS thin film is a potential and durable candidate for photocatalysis.
