Abstract
The practical application of carbon-supported Pt-based catalysts for the oxygen reduction reaction (ORR) in proton
exchange membrane fuel cells (PEMFCs) still faces many limitations, including carbon corrosion and their weak
interaction with Pt-based nanoparticles (NPs). Harnessing the strong metal-support interaction (SMSI) effects at
the interface between Pt-based nanoparticles and alternative corrosion-resistant non-carbon support is an
effective strategy to address these issues. The rational design of Pt-based catalysts with favorable SMSI and
elucidation of the mechanisms underlying such interactions is indispensable for achieving desirable activity and
stability. In this review, first, the basic principles of the ORR are briefly introduced. Next, the formation process of
SMSI, construction strategies, and the advantages and drawbacks of representative supports, including transition
metal oxides, nitrides, and carbides (TMOs, TMCs, and TMNs, respectively), are fully discussed. Finally, the
challenges and prospects in promoting the practical applications of the SMSI effect for ORR are highlighted.
