Abstract

Graphical abstract: Highlights: Recent novel developments of design, tailored synthesis, and ORR performances based on highly open Pt-based nanoarchitectures are summarized. Representative five highly open Pt-based nanoarchitectures are reviewed. The structure-dependent ORR performances and challenge are discussed. Abstract: Developing highly efficient and stable platinum (Pt)-based electrocatalysts for oxygen reduction reaction (ORR) is the most essential step toward the commercialization of fuel cells. Highly accessible reactive surfaces play a key role in boosting ORR for superior fuel cell performance due to the adequate exposure of the active surfaces and the feasible mass transport. Herein, we begin with a brief introduction to the design principles for an effective ORR electrocatalyst, which could plausibly possess high activity and durability at the same time. Corresponding with the requirements, the recent progress of rational design based on nanoarchitecture, synthesis, and electrochemical performances of Pt-based electrocatalysts with open construction is reviewed and explained accordingly.
