Electrocatalysis as a catalytic process involving oxidation or reduction through the direct transfer of electrons is of key importance subject in various fields of chemistry and associated sciences. Heterogeneous electrocatalysis is especially important to the development of water oxidation and fuel cells catalysts. This paper presents the brief description of the electrocatalysis and the mechanism of electrochemical reactions. Different factors and their influence on electrocatalytic activity, have been discussed. Role of nanoparticles in electrocatalysis received a particular emphasis. Long-term tasks of electrocatalysis were also definied.
