摘要
硅(Si)半导体材料作光电极用于光电催化(PEC)分解水制氢被认为是解决新能源问题比较有希望的措施之一.但目前Si基光电极也面临着光利用率低、不稳定、表面反应动力学缓慢等瓶颈.我们总结了目前Si基光电极材料的发展现状,从表面微纳米结构的设计、保护层的选择、助催化剂的改性3个提高光电极效率的途径,对Si基光电极材料的性能进行了介绍,并对其在该领域的发展前景进行展望.
The use of silicon(Si)semiconductor materials as photoelectrodes for photoelectrocatalysis(PEC)water splitting to produce hydrogen is considered one of the promising measures to solve the problem of new energy.However,currently,Si based photoelectrodes also face bottlenecks such as low light utilization,instability and slow surface reaction kinetics.This article summarizes the current development status of Si based photoelectrode materials and introduces the performance of Si based photoelectrode materials through three ways to improve photoelectrodes efficiency:design of surface micro-nano structures,selection of protective layers and modification of cocatalyst.The development prospects of Si based photoelectrode materials in this field are also discussed.
