Photoelectrocatalysis Hydrogen Production Using Silicon Based Photoelectrodes
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.
