摘要

以二(2-羟基丙酸)二氢氧化二铵合钛（TBA）和氧化石墨烯（GO）为前驱体，通过水热法合成出不同TiO₂含量的TiO₂/Graphene（TiO2/G）复合材料，随之用微波醇热法还原Pt前驱体可得Pt-TiO₂/G催化剂. 实验结果表明，TiO₂可与Pt相互作用，添入适量TiO₂的Pt-TiO₂/G催化剂具有较高的氧还原电催化活性及甲醇氧化的电催化活性与稳定性. 但TiO₂电导率偏低，过量TiO₂的添入反而使其电催化性能降低.

Abstract

A series of graphene-supported TiO₂ nanoparticles (TiO₂/G) with different TiO₂ contents were prepared by a facile hydrothermal method, and then the Pt-TiO₂/G catalysts were successfully prepared by reducing Pt-precursor with microwave technique. Compared with Pt-G catalysts, the catalytic performance toward oxygen reduction reaction (ORR) and methanol oxidation reaction (MOR) of Pt-TiO₂/G catalysts was improved due to the addition of TiO₂. However, the excessive TiO₂ would lead to a poor catalytic performance of Pt-TiO₂/G catalysts because of the low electrical conductivity of TiO₂.

Key words： TiO₂; graphene; ORR; methanol oxidation
