原子精密电催化剂的制备

Preparation of Atomically Precise Electrocatalysts

在各种阴极氧还原反应(ORR)的催化剂中,原子精密电催化剂(包括单原子、双原子和多原子团簇)因较高的原子利用效率和优异的催化性能,受到人们的关注。但ORR过程非常缓慢,阻碍了燃料电池作为下一代绿色能源设备的商业化。因此,开发高性能、低成本的ORR电催化剂,提高燃料电池的能量转换效率非常迫切。为了提高ORR的性能,研究者展开了大量的研究,以微调它们的结构和识别活性位点。本文对目前原子精密电催化剂的合成策略以及相关的设计进行了总结。

Among the various of efficient cathode oxygen reduction reaction(ORR)catalysts,atomic precision electrocatalysts(included single-atom,diatomic and multi-atomic clusters)were attracted more and more attention due to their high atomic utilization efficiency and excellent catalytic performance.However,the ORR process was very slow,hindering the commercialization of fuel cells as a next-generation green energy device.Therefore,it was urgent to develop high-performance and low-cost ORR electrocatalysts to improve the energy conversion efficiency of fuel cells.In order to improve the performance of ORRs,extensive research were conducted to fine-tune their structure and identify active sites.In this article,the current synthesis strategy and related design of atomic precision electrocatalysts were summarized.
