A photocatalyst composed of TiO2 nanotube arrays (TNTs) and octahedral Cu2O nanoparticles was fabricated, and its performance in the photocatalytic reduction of CO2 under visible and simulated solar irradiation was studied. The average nanotube diameter and length was 100 nm and ~5 μm, respectively. The different amount of octahedral Cu2O modified TNTs were obtained by varying electrochemical deposition time. TNTs modified with an optimized amount of Cu2O nanoparticles exhibited high efficiency in the photocatalysis, and the predominant hydroc...

光催化还原CO2生成烃类燃料是一种可同时解决全球变暖和能源危机问题的最有效途径之一.尽管这方面的研究已经取得了一定的进展,但是整体的光催化转换效率还非常低.因此,需要发展更加高效的催化剂.由于半导体材料禁带宽度与太阳光谱相匹配,人们已经对其进行了广泛研究.其中Ti O2因具有无毒、强氧化性以及良好的光学和电学性质等而成为最主要的研究对象.但是对于光催化还原CO2反应来说,Ti O2仍存在很多不足,如只能吸收太阳光谱中的紫外光,光生载流子会快速结合,以及光生空穴的强氧化能力等,这些都限制了其光催化还原CO2的效率.采用窄禁带宽度半导体修饰Ti O2是解决上述不足的有效途径之一.本文采用...
