Abstract
In this paper, novel CdSe/NH2-MIL-101(Cr) nanocomposites for photocatalytic hydrogen production were synthesized. When the prepared NH2-MIL-101(Cr) MOFs were modified with CdSe QDs, the photocatalytic hydrogen production amount was significantly increased and reached to 17,664 μmol g−1 in 7 h. The formation of CdSe/NH2-MIL-101(Cr) nanocomposites enhanced the light absorption intensity, broadened the visible light absorption range, promoted the transfer of photogenerated electrons and inhibited the recombination of photogenerated electron–hole pairs, then effectively improved the photocatalytic hydrogen production performance. In addition, the CdSe/NH2-MIL-101(Cr) nanocomposites exhibited high cycle stability, which was beneficial to the practical application in photocatalytic hydrogen production.
