Ce-based organic framework enhanced the hydrogen evolution ability of ZnCdS photocatalyst
2021
Abstract Ce-based organic framework materials [UIO-66(Ce)] were prepared, and the UIO-66(Ce)/ZnCdS composite was attained by microwave irradiation. Moreover, the photocatalytic hydrogen production activity was evaluated. The experimental results revealed that the ZnCdS nanoparticle was decorated on the surface of UIO-66(Ce), and the hydrogen production ability of ZnCdS nanoparticle was improved by UIO-66(Ce) significantly. The hydrogen production yield of UIO-66(Ce)/ZnCdS reaches 3.958 mmol/g·h, in which is as about 1.95 times as that of ZnCdS (2.031 mmol/g·h). The improvement for photocatalytic hydrogen production yield is because UIO-66(Ce) can facilitate the photoinduced carriers to separating.
