UiO-66基复合材料在光催化制氢方面的研究进展

Research progress of UiO-66 based composites for photocatalytic to produce hydrogen

  • 摘要: UiO-66作为一种金属有机框架材料, 不仅继承了金属有机框架材料所具有的高比表面积、多活性位点、易调整等特点, 同时还表现出类半导体的行为。UiO-66展现出的多孔环境非常有利于光生载流子的快速转移, 而且UiO-66的能带也符合光催化分解水的要求。但因其禁带宽, 只能对紫外光响应, 所以需要对UiO-66进行改性。本文综述了近年来UiO-66复合材料的设计、合成及在光催化制氢方面的研究进展, 分析讨论了UiO-66复合材料中存在的问题, 并对UiO-66用于光催化制氢前景进行了展望。

     

    Abstract: As a metal-organic framework material, UiO-66 inherits the characteristics of metal-organic framework material, including high specific surface area, multiple active sites and tunable porous structures, as well as exhibits semiconductor-like behaviors.The porous structure of UiO-66 is very favorable for the rapid transfer of photogenerated carriers, and the energy band is also meets the requirements of photocatalytic water splitting.However, UiO-66 can only respond to ultraviolet light for its wide bandgap, so it is necessary to be modified.In this paper, the design, synthesis and research progress of UiO-66 composite in recent years are reviewed.The problems are analyzed and discussed, and the applications in photocatalytic hydrogen evolution are prospected.
