Abstract

The concern about global warming bound to CO2 emissions has shifted the attention of the scientific, industrial, and social communities from the mere use of cheap and abundant energy sources to the exploitation of renewable energies and the expansion of the relevant transmission network. Within this frame, H2 is progressively assuming the role of preferred energy vector thanks to i) its abundance, it is possible to obtain from water (photo-)electrolysis; ii) its “combustion products”, water, without any other by-product when used in Fuel Cells. In this review, the attention is focused on Pt-based electrocatalysts, in term of chemical composition, morphology and size with the aim of reducing the content of the precious metal, used to prepare electrodes for the Oxygen Reduction Reaction in alkaline media.
