本论文以探究Au对O2气氛下的立方Gd2O3（c-Gd2O3）表面过氧物种光诱导生成的促进作用为目的，探索了不同制备方法、Au负载量、样品的浸渍时间、焙烧温度、还原温度、激光功率、样品温度以及Au的粒径大小等因素对过氧物种生成的影响，主要研究结果如下： (1)在紫外激光（325nm）照射下考察了Au对c-Gd2O3表面过氧物种光诱导生成的促进作用。结合ICP、TEM、HAADF-STEM和XRD等表征方法对样品进行分析。研究表明，在室温和O2气氛下，未经高温通O2处理的c-Gd2O3表面经激光照射后未检测到过氧的Raman谱带，而在相同的实验条件下，采用浸渍法、光还原法和沉积沉淀法制备的Au...This dissertation aimed to the studies of the promotion mechanism and influencing factors of Au for photo-induced formation of peroxide species on the surface of cubic Gd2O3 (c-Gd2O3) in the presence of oxygen. The influences of several variable parameters, such as the preparation methods, gold loading, impregnation time, temperature, laser power and size of gold nanoparticles, were investigated c...学位：理学硕士院系专业：化学化工学院_物理化学学号：2052013115159
