Electrocatalysts often appear as small-sized metals or even single metal atoms on various support materials or matrix. In this talk, I will present a novel synthetic method to prepare supported metal electrocatalysts directly from their corresponding bulk metals, namely a top-down approach, bypassing the conventional metal ion reduction process. The electrocatalysts prepared by this method are free of any counter-ions, ligand molecules, reducing agents, surfactants and other complications inevitably inherited from the traditional metal ion reduction methods. The cleanness and the intrinsic nature of such a top-down method produce astonishing electrocatalytic performance in electrical energy conversion to storable liquid fuels and electrical energy storage schemes. Our atomic level experimental and theoretical efforts also provide a mechanistic understanding of the elementary processes attributing to the outstanding electrochemical performance of these electrocatalysts.<br/><br/>
