英文摘要 | Developing catalysts with high electrocatalytic activity for oxygen reduction reaction (ORR) has recently attracted much attention because the sluggish ORR limits the performance and commercialization of current PEMFCs and metal-air batteries as well. Herein, a facile approach was reported to synthesize Mn3O4 nanoparticle coated carbon nanotubes (Mn3O4/CNTs) and self-deposit well-dispersed Pt nanocrystals on Mn3O4/CNTs to obtain Pt/Mn 3O4/CNTs hybrid catalysts via in situ reduction of support matrix with no need of any capping agent and additional reducing agent. As a result of good dispersion of uncapped Pt nanocrystals, interconnected carbon nanotube conductive network, and possible synergetic co-catalytic effect from heterojunction interfaces of Pt nanocrystals and Mn3O4, the as-prepared Pt/Mn3O4/CNTs hybrid catalysts demonstrated much enhanced electrocatalytic activity for ORR. The reported strategy may inspire the development of new high efficient hybrid electrocatalysts in a cost-effective way with the potential to harness the metal/oxide interaction to improve the performance of catalysts.
