Research: Electrocatalyst Synthesis and Development

Electrocatalysts are materials that increase the rate of electrochemical transformations and reduce the energy losses needed for such transformations. Typically, electrocatalystsare noble metal nanoparticles, anchored on the surface of an inert and stable compound. Different electrochemical reactions and conditon require diverse electrocatalytic materials.

In Laboratory for Electrocatalysis we focus mostly on reactions that are central to electrochemical energy transformations, namely electrochemical transformations of water, hydrogen and oxygen. Additionally, we also study methanol oxidation and carbon dioxide reduction.
