A method of forming an electrode including an electrochemical catalyst layer is disclosed, which comprises forming a graphitized porous conductive fabric layer, optionally conditioning the graphitized porous conductive fabric layer, and dipping the graphitized porous conductive fabric layer into a solution containing a plurality of polymer-capped noble metal nanoclusters dispersed therein. The polymer-capped noble metal nanoclusters as an electrochemical catalyst layer are adsorbed onto the graphitized porous conductive fabric layer. An electrochemical device with the electrode made thereby is also contemplated.
