摘      要：Oxygen reduction reaction(ORR)is considered the bottleneck reaction in fuel *** sluggish kinetics requires the use of scarce and expensive platinum group metal(PGM)*** efforts have been invested in trying to find a PGM-free catalyst to replace Pt for this reaction or reduce its *** interesting family of materials that has shown great promise in doing so is aerogels,which are based on covalent *** aerogels’high surface area and porosity enable good mass transport and high catalyst utilization that is expected to lower PGM loadings or replacing them *** review summarizes recent research in this field,introducing methods of using aerogels as cathodes for ORR,from carbon to metal *** catalytic sites vary from nanoparticles to atomically dispersed metal ions embedded in carbon aerogels that form all-in-one platform which can serve as both the support and the catalyst.
