| Summary: | 碩士 === 國立高雄應用科技大學 === 化學工程與材料工程系 === 97 === This paper describes a method for size-controlled synthesis of Pt nanoparticles and their attachment to the sidewalls of multwall carbon nanotubes (CNTs) by self-regulated reduction of sodium n-dodecyl sulfate (SDS), without surface pretreatment. The size of the Pt nanoparticles is controlled by adjusting the concentration of SDS. When Pt/CNTs are heated to 500℃ in N2 atmosphere, Pt nanochains are formed on the CNTs; some of these nanochains contain small islands. Electrochemical measurements confirm that the electroactivities of the Pt/CNTs nanocatalysts increase with a decrease in the size of the Pt nanoparticles, the heated Pt/CNT nanocatalysts containing Pt nanochains with small Pt islands show higher electrocatalysis activities and stability.
