为了提高TiO2光催化剂分解水的效率，研究了铂沉积方法和铂浓度对铂沉积TiO2光催化剂产氢速率的影响。在本研究所用的方法中，甲醇法的H-2产率最高。为了获得最高的产氢率，必须优化二氧化钛上的铂含量。用这种方法制备的铂沉积的二氧化钛表面的铂颗粒太小或太薄，用透射电子显微镜观察不到。(C)2006年国际氢能协会。爱思唯尔有限公司出版。保留所有权利。
In order to increase the effectiveness of water splitting by TiO2 photocatalysts, the effects of the Pt deposition method and the Pt concentration on the hydrogen production rate of Pt-deposited TiO2 were studied. Among the methods used in this study, the formaidehyde method resulted in the highest rate of H-2 production. The amount of Pt on TiO2 had to be optimized to obtain the highest rate of H2 production. The Pt particles on the Pt-deposited TiO2 prepared by the present method were too small or too thin to be observed by transmission electron microscopy.
