Abstract
Official abstract text for this publication.
A process includes patterning a surface of a platinum group metal-based electrode by contacting the electrode with an adsorbate to form a patterned platinum group metal-based electrode including platinum group metal sites blocked with adsorbate molecules and platinum group metal sites which are not blocked.
First claim
Opening claim text (preview).
What is claimed is: 1. A process comprising: patterning a surface of a platinum group metal-based electrode by contacting the electrode with an adsorbate and electrochemically cycling the electrode in an oxygen saturated solution to form a patterned platinum group metal-based electrode comprising platinum group metal sites blocked with adsorbate molecules and platinum group metal sites which are not blocked. 2. The process of claim 1 , wherein the platinum g…
