摘　　要：光催化剂是指在光子激发的前提下,表现出催化作用的所有化学物质。例如,促进水与二氧化碳合成的叶绿素。首先介绍了什么是"光催化剂",其次以SO42-/TiO2、TiO2为切入点,围绕其光谱行为展开了一系列实验,最后结合实验现象和结果,深入分析了二者的光谱行为。PHotocatalyst refers to all the chemical substances that exhibit catalysis under the condition of pHoton excitation.For example,chloropHyll,which promotes the synthesis of water and carbon dioxide.This paper first introduces what is "PHotocatalyst".Then,with SO42-/TiO2 and TiO2 as the breakthrough point,a series of experiments are carried out around their spectral behavior.Finally,combined with the experimental pHenomena and results,the spectral behavior of them is analyzed in depth.
