475978 Electrodeposition As a Method to Prepare Thin Film Electrocatalysts for Renewable Energy Application
Electrodeposition is a simple, scalable method to prepare materials on many substrates, and is highly tunable as the electrolytic conditions and electrochemical technique affect film growth. In addition to being scalable and versatile, electrodeposition is beneficial to electrocatalysis as the intimate substrate connection allows for more rapid charge transfer, and no pretreatment (e.g. binders that can decrease surface adsorption) is necessary to ensure adhesion or stability. Thus, we have developed thin film electrodepositions for ORR, OER, and HER electrocatalysts with promising fundamental results and scalable possibilities for device fabrication. Our NixCo3-xO4 bifunctional oxygen electrocatalysts, a CoP bifunctional water splitting electrocatalyst, and a MnOx/PEDOT ORR electrocatalyst will be highlighted and examined for their promise as catalyst materials for next-generation energy conversion and storage devices.
