| 摘 要： | 目的:开发高效廉价的氧还原反应催化剂。方法:采用超声剥离法,以商业SiC为原料,成功获得了超薄纳米SiC催化剂,对其形貌进行了表征,并对其催化氧还原(ORR)性能进行研究。结果:超声处理能有效地剥离商业SiC,获得超薄催化剂。超薄纳米SiC催化剂对氧还原反应的起始电位和电流密度均与商业Pt/C催化相近,氧还原反应以4电子路径为主,在较低电位下能获得较大的动力学电流。结论:本实验制备的超薄催化剂,有望作为高效低成本燃料电池的潜在材料。

| Abstract: | Objective:Exploiting an low-cost and efficient catalyst for the oxygen reduction reaction is of great significance to promote the industrialization of fuel cell.Method:Ultr-athin nano SiC catalyst has been obtained successfully by ultras-onic exfoliation method derived from commercial SiC.The morphology and catalytic performance for oxygen reduction reaction (ORR) have been characterized.Results:The results showed that the commercial SiC can be exfoliated effectively by ultrasonic and obtained ultrathin catalyst.The onset potential and current density of the ultrathin SiC catalyst for oxygen reduction reaction were similar to that of commercial Pt/C.The oxygen reduction reaction was dominated by 4-electron path and the larger kinetic current was obtained at lower potential.Conclusion:The ultra-thin catalyst prepared in this experiment is expected to be a potential, low-cost and efficient catalytic material for fuel cells. |
