Carbonaceous and alternative supporting materials for platinum (Pt) and palladium (Pd) have been explored for the cathodic electrocatalysis in low-temperature fuel cells. Pd and Pt are widely used for catalysis owing to their remarkable electrocatalytic activity toward water splitting and fuel cell reactions. Supporting materials play a paramount role in defining electrocatalytic properties such as durability, selectivity, and activity. The conven-tional supporting material such as carbon black is unable to fit all the requirements under the severe operating conditions of fuel cells due to its poor corrosion resistance and limited mass transport of fuels to active catalyst sites. Nowadays the scientific research is being concentrated on devising different altered carbonic and carbon-free supporting materials for catalysts to improve the catalytic activity, stability, and selectivity of noble metal electrocatalysts. Lately, Pt, Pd and their alloy catalysts supported on modified carbonaceous and carbon-free materials have attracted solid interest owing to their prominent characteristics contributing to the remarkable fuel cell efficacy. Therefore, it is reasonable to explore this theme, regarding a variety of supporting materials, their advantages, drawbacks and future perspectives. In this mini-review, we selectively summarize recent ad-vancements on several types of key supporting materials: carbon (graphene, carbon nanotubes, mesoporous carbon, and doped carbon nanostructures), non-carbon (transition metals oxides, borides, nitrides, and carbides) and hybrid nanocomposites.
