Metal-Organic Framework-Derived Fe-N-C Nanohybrids as Highly-Efficient Oxygen Reduction Catalysts
开发用于氧还原反应(ORR)的低成本和高性能的非贵金属催化剂(NPMC)对于燃料电池的商业化至关重要.在这里,我们介绍了一种简单合成的由Fe3C纳米粒子包裹在介孔N掺杂碳(Fe-NC)中的NPMC材料,包括MIL-100(Fe)与葡萄糖和尿素的物理混合,以及随后在惰性气体下的热解.由此获得的Fe-N-C-900(在900℃下制备的材料)表现出优异的电催化活性,高耐久性和对ORR卓越的甲醇耐受性,其催化性能与商业Pt/C在碱性介质中的催化性能相当.…查看全部>>
Environmentally friendly and renewable energy technologies,such as fuel cells and metal-air batteries,hold great promise for solving current energy and environmental challenges.The oxygen reduction reaction (ORR) plays a pivotal role in this top-drawer question.However,the sluggish kinetics of the ORR and prohibitive costs limit the global scalability of such devices.Traditionally,platinum-based electrocatalysts exhibit the best performance for ORRs in both …查看全部>>
