高分散度Pt-Ir疏水催化剂制备及氢-水液相交换催化性能研究（Highly Dispersed Pt-Ir Hydrophobic Catalysts: Preparation and Catalytic Activity for Hydrogen-water Liquid Exchange Reaction）
疏水催化剂 氢-水液相催化交换 氢同位素分离 微波加热法 Pt-Ir/C
2010/8/18
用乙二醇作为碳黑分散溶剂，微波辐射快速加热，1～2 MPa压力下制备了Pt/C及不同Pt、Ir比例的Pt-Ir/C催化剂，用浸渍还原法制备了Pt-Ir/C催化剂，并用XRD，TEM和XPS对催化剂进行了表征。将两种方法制备的Pt/C，Pt-Ir/C催化剂与聚四氟乙烯(PTFE)一起负载于多孔金属载体，得到疏水催化剂，考查了其对氢-水液相交换反应的催化活性。微波辐射加热法制备的Pt/C和Pt-Ir...
