Photochemical Synthesis of Composite Noble Metal Nanoparticles for Fuel Cell Catalysts
[摘要] Direct methanol fuel cell is an ideal way for energy use because of its low noise, simple structure, rich fuel source, low price, easy storage and transportation. However, in the commercial application, it is necessary to overcome high catalyst cost and short life. The work used photochemical reduction and seed crystal growth to reduce PtII and PdII on the surface of Ag nanoparticles to form Ag@Pt-Pd core-shell composite nanoparticles with particle size of about 5∼10 nm. The results showed that the synthesized composite nanoparticles have good electrocatalytic activity, with good research and application in the electrode catalysts of fuel cells.
