【摘要】 本文基于连续微波管道反应器，采用强化传质策略，实现了PtCo/C催化剂的可控批量制备。通过系统对比连续微波管道法与传统双浸渍法和单浸渍法制备的催化剂，深入分析了不同合成工艺对催化剂微观结构和氧还原反应（oxygen reduction reaction,ORR）电催化性能的影响。研究结果表明：连续微波管道法制备的PtCo/C催化剂展现出最小且分布均匀的粒径（3.5 nm）、更高的电化学活性面积（electrochemical active area,ECSA）以及优异的ORR催化性能。此外，放大实验验证了该方法在大规模制备中的良好批次稳定性和工艺可行性。该研究为高效燃料电池催化剂的规模化生产提供了新的技术思路和实验依据。更多还原

【Abstract】 In this study, the controlled batch preparation of PtCo/C catalysts was realized based on a continuous microwave tubular reactor through enhanced mass transfer strategy.By systematically comparing the catalysts prepared by the continuous microwave tubular method with those prepared by the conventional double-impregnation and singleimpregnation methods, the effects of different synthesis processes on the microstructures of the catalysts and the electrocatalytic performances of the oxygen reduction reaction(ORR) were deeply analyzed.The results show that the PtCo/C catalysts prepared by the continuous microwave tubular method exhibit smaller and uniformly distributed particle sizes, higher electrochemical active area(ECSA), and excellent ORR catalytic performance. In addition,scale-up experiments verified the good batch stability and process feasibility of the method in large-scale preparation.This work provides a new technical idea and experimental basis for the large-scale production of efficient fuel cell catalysts.更多还原
