【摘要】 在不加保护剂的情况下,采用微波法合成了金属铂纳米颗粒,并负载到XC-72导电炭黑上。TEM结果显示,合成的未负载的铂纳米颗粒粒径小、粒径分布范围窄,平均粒径为2.5 nm,粒径分布的相对标准偏差为0.216。炭黑负载的铂纳米颗粒粒径与未负载时相当,且同期负载时,负载的铂纳米颗粒数量较多,负载效果好;而非同期负载时,负载的铂纳米颗粒数量少。更多还原

【Abstract】 Pt Nanoparticles were prepared and supported on XC72 carbon black by microwave method without any protecting agent.TEM examinations showed small diameters and narrow size distributions for unsupported Pt nanoparticles with an average diameter of 2.5 nm and a relative standard deviation of 0.216.The size distributions of Pt nanoparticles supported on carbon black were similar to the unsupported.The number and absorbing effect for Pt nanoparticles supported on carbon black simultaneously were better than those for supported unsimultaneously.更多还原
