针对3种不同类型的氧还原反应(ORR)催化剂(Pt基催化剂、非贵金属催化剂、非金属催化剂),比较和分析了它们的优缺点,Pt基催化剂催化活性好、制备工艺成熟,但储量少、价格昂贵;非贵金属催化剂价格低,但抗毒能力弱;非金属催化剂储量丰富、价格低廉、稳定性好。由此指出,非铂催化剂是今后的研究方向,并对其发展进行了展望。

Three different types of catalysts for oxygen reduction reaction,including Pt-based catalysts,non-precious metal catalysts and non-metallic catalysts,are mainly described.Their advantages and disadvantages are compared and analyzed.Pt-based catalysts exhibit good catalytic activity,and their preparation process is mature,but there is small reserve in Pt and Pt-based catalysts are expensive.Non-precious metal catalysts are cheaper but weak in anti-toxicity.Non-metallic catalysts have good stability and low cost,and their raw materials are abundant in reserve.Thus,it is pointed out that non-Pt catalysts are the research direction in the future and their development is prospected.
