摘要:

燃料电池技术的商业化进程主要受制于其阴极动力学缓慢的氧还原反应(ORR)所需的高铂量电催化剂,因此急需开发更高活性的电催化剂。过去十年里,人们在提高铂基催化剂ORR活性的研究取得了极大进展。本文概述了通过结构调控提升铂基纳米晶氧还原电催化性能的最新进展,依据纳米晶的空间维度展开讨论,同时列举各类电催化材料的优缺点。基于理论和实验结果,本文重点讨论铂基纳米晶应用于氧还原电催化的构效关系,以及其对下一代电催化材料结构设计方面的潜在指导意义。最后,我们对此领域未来的研究方向做了展望。

Abstract:

The past decade has witnessed tremendous progress in the improvement of the electrocatalytic efficiency of the oxygen reduction reaction (ORR), which is important for the widespread adoption of fuel cells. This review provides an overview of the recent advances in the rational structural design and construction of Pt-based nanocatalysts to achieve higher ORR activity, with an emphasis on tuning the dimensionalities of Pt-based nanocrystals. The advantages and disadvantages of each dimensional catalyst have been discussed. In particular, we focus on a contemporary understanding of the structure-performance relationships based on the combined theoretical and experimental evidence, which can be further applied to guide the search for more exciting catalytic systems. The review concludes with a personal perspective for future research directions.

Key words: Fuel cells, Oxygen reduction reaction, Platinum-based nanocrystals, Dimensionality tuning
