Ru-decorated as model fuel cell electrocatalysts for CO electrooxidation

A study is conducted to identify the role of ruthenium promoters in enhancing electrocatalytic activity toward organic fuels for fuel cells, with particularly concerns on the methanol decomposition product, surface CO. Different methods used to prepare Ru-decorated Pt single crystal surfaces while reviewing Ru-decorated Pt nanoparticles along with the methods of characterization and testing of their activity.
