Enhancement and Mechanism Clarification on CO2 Reforming Performance of Combined Photocatalyst Absorbing Wide Wavelength Range Light

本研究的主要目的是通过提高TiO2的还原性能，提高TiO2光催化剂转化为CH4、CO和H2等燃料的CO2重整性能。本研究旨在将可产生H2的钯与几种吸收波长范围不同的金属相结合，制备响应宽波长范围光的高性能光催化剂。用SEM和EPMA分析了制备的光催化剂的表面特性。此外，还在包括紫外光在内的宽波长光照射下以及可见光照射下进行了CO2重整实验，对CO2重整特性进行了评价。

The main goal of this study is improvement of CO2 reforming performance of TiO2 photocatalyst into fuel such as CH4, CO and H2 by improvement of reduction performance of TiO2. This study aims to prepare the high performancephotocatalyst responding to wide wavelength range light by combination of Pd which canproduce H2 and several metals with different absorption wavelength range light. The surface characteristic of prepared photocatalyst was analyzed by SEM and EPMA. In addition, CO2 reforming experiment was carried out under illumination of wide wavelength light including ultra violet light as well as under illumination of visible light, the characteristics of CO2 reforming was evaluated.
