Title: Methods for forming electrocatalyst structures and electrodes comprising same

Abstract

Described herein are methods of forming an electrocatalyst structure on an electrode, comprising depositing a first layer on the electrode using atomic layer deposition (ALD), wherein the first layer comprises a plurality of discrete nanoparticles of a first electrocatalyst, and depositing one or more of a second layer on the first layer and the electrode using ALD, wherein the one or more second layer comprises a second electrocatalyst, wherein the first layer and the one or more second layers, collectively, form a multi-layer electrocatalyst structure on the electrode. Also described are electrodes having a multi-layer electrocatalyst structure. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
