| 摘 要： | 利用高压微波消解仪密闭带压、升温速率可控的特点，选择XC-72碳黑为载体，乙二醇为碳黑分散溶剂和还原剂，研究反应温度、升温速率、水含量、Pt含量及表面活性剂等工艺条件对Pt粒子尺寸及其分散度的影响．研究结果表明，快速升温到190℃、控制反应体系中水含量和Pt含量等工艺条件，可以得到Pt粒子平均粒径小于3．1nm的Pt／C催化剂，且Pt粒子分布均匀，无团聚．

| Abstract: | The technical conditions of preparing Pt/C catalysts were investigated using Microwave Digestion Workstation,which has closed vessels for high pressure and controlled programs for heating.XC-72 Carbon is used as carrier,and ethylene glycol for reducing agent and disperse solvent of carbon.The conditions includes reaction temperature,heating speed,content of water,content of platinum,and surfactant.The experimental results show that carbon supported platinum nanoparticles less than 3.1 nm can be prepared by heating up to 190 ℃,controlling the content of water and the content of platinum in the reaction system.The synthesized platinum nanoparticls disperse well-proportioned on carbon surfaces. |
