An infrared spectroelectrochemical approach for understanding electrocatalysis at supported metal nanoparticles

Thesis

This thesis describes the development and application of a new in situ infrared (IR) approach to studying electrocatalysis at supported nanoparticle catalysts that are used in proton exchange membrane (PEM) fuel cells. Such fuel cells running on small organic molecules are an attractive technology for use in transport applications and portable electronic devices, however one major challenge facing this technology is the slow oxidation of the organic molecules at the electrode surface. Furt...
