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
