Abstract
A method of forming an electrode having an electrochemical catalyst layer is disclosed. The method includes etching a surface of a substrate, followed by immersing the substrate in a solution containing surfactants to form a conditioner layer on the surface of the substrate, and immersing the substrate in a solution containing polymer-capped noble metal nanoclusters dispersed therein to form a polymer-protected electrochemical catalyst layer on the conditioner layer.

A method of forming an electrode including an electrochemical catalyst layer, the method comprising:
- providing a substrate with a conductive layer formed on a surface of the substrate;
- etching the surface of the substrate;
- immersing the substrate in a first solution containing a surfactant to form a conditioner layer on the conductive layer after etching the surface of the substrate;
- immersing the substrate in a second solution to form a polymer-protected electrochemical catalyst layer on the conditioned layer, wherein the second solution contains polymer-capped noble metal nanoclusters dispersed in the second solution;
- and
- thermally treating the polymer-protected electrochemical catalyst layer at a temperature in the range of 350° C. to 425° C. to degrade the surfactant and the polymer of the polymer-capped noble metal nanoclusters.
