采用微波加热多元醇还原的方法制备了贵金属Pt负载的TiO2纳米管复合材料,并对其形貌和结构进行了表征。结果表明,试验中所制备的TiO2纳米管直径约10nm左右,长度达到几百纳米甚至微米级。微波法负载的Pt粒子粒径分布均匀,尺寸约在4.5nm左右。电化学结果表明该复合纳米材料对甲醇具有一定的催化氧化作用。
The noble metal Pt-supported TiO2 nanotubes composites were prepared by microwave heating and polyol reduction. The morphology and structure of the composites were characterized. The results show that the diameter of TiO2 nanotubes prepared in the experiment is about 10nm and the length reaches several hundred nanometers or even micrometers. Pt particle size distribution of microwave load evenly distributed, the size of about 4.5nm. Electrochemical results show that the composite nanomaterials have a certain catalytic oxidation of methanol.
