Abstract:

Hollow nanostructures have been receiving great attention for structural design and electrocatalytic applications in energy conversion and storage due to their large specific area, tunable mass transfer rates, and well-defined active sites. Especially when hollow precious metal-based nanostructures are used as oxygen reduction reaction(ORR) electrocatalysts, the introduction of interior cavity in hollow precious metal-based nanostructures(HPMs) can expose more active sites and reduce the amount of costly precious metals, which will provide a desirable platform to achieve their large-scale applications. Herein, recent progress on synthesis and ORR application of the HPMs is summarized. First, a brief review of the advantages and significance for developing HPMs towards ORR is given. Further, four main strategies to synthesize HPMs, including hard-, soft- and self-template methods, as well as template-free methods, are explicitly described in terms of recent advances and their advantages. Finally, the remaining challenges and promising solutions are summarized to provide some useful clues for the future development of the HPMs in ORR field.
