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

An efficient visible light responsive ZnIn2S4@NH2-MIL-53(Fe/Co-0.75) nanocomposite was prepared for photocatalytic hydrogen production application. Under visible light irradiation, the ZnIn2S4@NH2-MIL-53(Fe/Co-0.75) photocatalyst displayed improved photocatalytic performance and the hydrogen production rate reached to 161724.8 mu mol/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 ZnIn2S4@NH2-MIL-53(Fe/Co-0.75) nanocomposite as a high-efficiency photocatalyst would have broad prospect for water splitting hydrogen production application.
