中文摘要：
采用CO作为探针分子,将原位透射红外光谱应用于研究助催化剂Pt在Pt/TiO2光催化体系中的作用。实验发现,光照条件下, CO的覆盖度及样品温度没有明显变化, CO在Pt/TiO2上的吸附峰红移11cm-1,在Pt/Al2O3上的吸附峰没有位移,表明CO在Pt/TiO2上的红移来源于TiO2上的光生电子转移到Pt上,这解释了为什么加入Pt助催化剂可提高光催化产氢活性。
英文摘要：
In situ transmission infrared spectroscopy was used to study the role of Pt cocatalyst in Pt/TiO2 using CO as a probe molecule. An 11 cm-1 redshift of CO adsorbed on Pt/TiO2 was observed under irradiation in the absence of changes in the CO coverage or sample temperature. In contrast, no CO shift was detected on Pt/Al2O3. This indicates that the redshift of the CO adsorption peak is due to the photogenerated electron transfer from TiO2 to Pt, and this accounts for the increased photo-catalytic activity by the loaded Pt cocatalyst.
