本文通过简单溶剂热反应合成棒状SnO2,然后以谷氨酸为添加剂,乙二醇为分散剂和还原剂,溶剂热合成SnO2纳米棒负载的Pd-Cu球形空壳催化剂.透射电镜结果表明Pd-Cu空心球粒径大约100 nm,并且分布均匀.电化学测试结果表明,该催化剂对乙醇氧化表现出较高的电催化活性和稳定性,其中电流密度可达119.4 mA cm?2,研究表明,合适的金属氧化物的引入可使催化剂释放更多的活性位点从而提高催化剂的电催化活性.
In this paper, rod-shaped SnO2 was synthesized by simple solvothermal reaction, and then Pd-Cu spherical hollow shell catalysts supported on SnO2 nanorods were synthesized by using glutamic acid as an additive and ethylene glycol as a dispersant and a reductant.The results of transmission electron microscopy showed that Pd- Cu hollow spheres have a diameter of about 100 nm and are evenly distributed.The results of electrochemical tests show that the catalyst exhibits high electrocatalytic activity and stability to ethanol oxidation with a current density of 119.4 mA cm • 2, The introduction of a suitable metal oxide allows the catalyst to release more active sites thereby increasing the electrocatalytic activity of the catalyst.
