A Facile One Step Synthesis of MoS2/g-C3N4 Photocatalyst with Enhanced Visible Light Photocatalytic Hydrogen Production

Noble metal-free MoS 2 /g-C 3 N 4 photocatalysts have been synthetized by one step thermal treatment of thiourea and sodium molybdate, which has intimate contact interfaces between g-C 3 N 4 and MoS 2 . The hydrogen generation rate of MoS 2 /g-C 3 N 4 photocatalyst is 280 µmol·g −1 ·h −1 , 40 times...

Zusammenfassung:Noble metal-free MoS 2 /g-C 3 N 4 photocatalysts have been synthetized by one step thermal treatment of thiourea and sodium molybdate, which has intimate contact interfaces between g-C 3 N 4 and MoS 2 . The hydrogen generation rate of MoS 2 /g-C 3 N 4 photocatalyst is 280 µmol·g −1 ·h −1 , 40 times as that of pristine g-C 3 N 4 . The enhanced activity is attributed to the in-situ generated intimate interfaces, which leads to enhanced absorption of visible light and higher efficiency of charges separation. Graphic Abstract
