In this work, a review of articles and patents related to the utilization of colloidal metal nanoparticles produced
by the decomposition of organometallic precursors as supported electrocatalysts in different electrochemical reactions including
hydrogen evolution reaction (HER), oxygen reduction reaction (ORR) and methanol oxidation reaction (MOR) is
discussed. In the case of stabilized metal nanoparticles, the kind of functional group contained in the stabilizer as well as
the metal/stabilizer ratio, to evaluate the effect of particle size on the electrochemical performance, were also debated. Potential
applications and perspectives of these electrocatalysts in proton exchange membrane fuel cells (PEMFC) are contended
with reference to the role played by the coordination compounds and costs.
