ZnIn2S4 decorated Co-doped NH2-MIL-53(Fe) nanocomposites for efficient photocatalytic hydrogen production

An efficient visible light responsive ZnIn 2 S 4 @NH 2 -MIL-53(Fe/Co 0.75 ) nanocomposite was prepared for photocatalytic hydrogen production application. Under visible light irradiation, the ZnIn 2 S 4 @NH 2 -MIL-53(Fe/Co 0.75 ) photocatalyst displayed improved photocatalytic performance and the hydrogen production rate reached to 161724.8 μmol/g in 6 h. The nanocomposite with large specific surface area and mesoporous structure increased the light absorption, improved the electrons transfer and suppressed the recombination of photogenerated electron-hole pairs, thus exhibiting efficient photocatalytic hydrogen production performance. The controllable synthesis of ZnIn 2 S 4 @NH 2 -MIL-53(Fe/Co 0.75 ) nanocomposite as a high-efficiency photocatalyst would have broad prospect for water splitting hydrogen production application.
