Size dependent photogeneration charge carrier density of hollow ZnIn2S4 microspheres for enhanced photocatalytic activity

Enhanced photocatalytic hydrogen activities of CoV-LDH/ZnIn2S4 nanocomposites

“…6–8 Since Lei et al first discovered in 2003 that the ZnIn 2 S 4 photocatalyst synthesized by a hydrothermal method has an excellent photocatalytic ability of water splitting to produce hydrogen under visible light, the majority of scientific researchers have turned their research attention toward ZnIn 2 S 4 -based photocatalysts. 9–12 As a typical transition chalcogenide semiconductor, ZnIn 2 S 4 is widely used in photocatalytic water splitting due to its unique crystal structure, suitable band gap and excellent visible light response. 13 However, due to the easy recombination of photogenerated electron and hole pairs, the carrier transfer efficiency is low and the photocatalytic activity is limited.…”
