摘要:

在光催化过程中, 光催化剂被太阳能激发产生光生电子和空穴, 来实现环境净化或能量转换, 是应对全球变暖和能源短缺的有效途径之一. 然而, 光催化技术面临的主要瓶颈问题是光生载流子的低分离效率和高反应能垒. 而催化剂本身的特性对这一点起到了决定性的作用. 因此, 催化剂的合理设计和改性是提高光催化效率的关键. 金属有机框架(MOFs)是一类由金属节点和有机配体组成的新型结晶多孔材料. 基于结构多样性、超高比表面积、形状和尺寸可调的纳米孔或纳米通道等优异的特性, MOFs基材料在光催化领域引起了广泛关注. 然而, MOFs的主要问题之一是低导电性和稳定性, 这限制了其更广泛应用.
正是由于MOFs的不稳定性, 其可以作为牺牲模板制备纳米材料. 由MOFs衍生的纳米材料继承了MOFs的优异特性, 同时避免了MOFs较差的导电性和稳定性的问题. 并且可以通过选择特定的金属节点和有机配体对MOFs衍生的纳米材料进行调控, 从而实现光催化剂的多功能性. 因此, MOFs衍生物在光催化领域展现出更广阔的应用前景. 而且MOFs衍生物不仅可以作为半导体光催化剂, 还可以作为光催化析氢、CO2还原、污染物降解等反应的助催化剂.
本文重点介绍MOFs衍生物在光催化领域的多功能应用. 从MOFs衍生物的制备、修饰和应用等方面对近年来的研究进行了分析和总结. 最后, 对MOFs衍生物应用于光催化领域的挑战进行了分析, 并对未来发展和机遇进行了展望, 以期为该领域的进一步研究提供更多参考, 并带来新的启示.

Abstract:

Metal-organic framework (MOF)-derived nanomaterials have attracted widespread attention, because the excellent features, such as high surface area, porosity and tunable properties are inherited from MOFs. Moreover, the derivatives avoid the poor conductivity and stability of MOFs. MOF-derived nanomaterials can easily be regulated by a specific selection of metal nodes and organic linkers, resulting in multifunctionality in photocatalysis. MOF derivatives can be used not only as semiconductor photocatalysts, but also as co-catalysts for photocatalytic hydrogen evolution, CO2 reduction, pollutants degradation, etc. This review focuses on the multifunctional applications of MOF derivatives in the field of photocatalysis. The researches in recent years are analyzed and summarized from the aspects of preparation, modification and application of MOF derivatives. At the end of the review, the development and challenges of MOF derivatives applied in photocatalysis in the future are put forward, in order to provide more references for further research in this field and bring new inspiration.
