近年来,光电催化技术(PEC)因其融合了电化学与光催化技术的优势而备受瞩目.这一技术不仅展现了优良的催化性能,还解决了传统粉末光催化剂难以分离回收的难题.光电极的基底材料是P E C技术的核心,其显著影响着电子转移的效率、光生载流子的复合率以及光电极的稳定性.尽管PEC技术已取得诸多成果,但关于光电极基底材料的研究进展尚未得到充分的文献报道.鉴于此,在系统地对光电极基底材料进行分类,包括金属、导电玻璃、碳基材料以及其它新兴材料,并深入回顾近年来关于这些材料的研究进展.详细论述光电极的制备方法、性能表现以及作用机理,以期为读者提供一个全面而深入的理解.同时,我们也对光电极基底材料的未来研究方向提出了一些建议,希望能为该领域的进一步发展提供有益的参考.
Research progress of substrate materials for photoelectrodes in photocatalysis
In recent years,photocatalytic technology(PEC)has attracted much attention due to its integration of the ad-vantages of electrochemistry and photocatalytic technology.This technology not only shows excellent catalytic perform-ance,but also solves the problem that the traditional powder photocatalyst is difficult to separate and recycle.The sub-strate material of photoelectrode is the core of PEC technology,which significantly affects the efficiency of electron transfer,the recombination rate of photogenerated carrier and the stability of photoelectrode.Although PEC technology has made many achievements,the research progress of photoelectrode substrate materials has not been fully reported.In view of this,this paper aims to systematically classify the substrate materials of photoelectrode,including metals,con-ductive glass,carbon-based materials and other emerging materials,and review the recent research progress on these materials.The preparation method,performance and mechanism of photoelectrode are discussed in detail in order to pro-vide readers with a comprehensive and in-depth understanding.At the same time,we also put forward some suggestions on the future research direction of optical electrode substrate materials,hoping to provide useful reference for the further development of this field.
