Electrochemical science and engineering are at the forefront in many technologies focusing on alternative energy sources (fuel cells, batteries, supercapacitors), pollution control of gaseous (e.g. CO2, NOx) and liquid effluents and environmentally more sustainable chemical process development (e.g. the electrosynthesis alternative to conventional thermochemical processes).
The commercial development of many electrochemical systems, including a variety of fuel cell types and batteries, pollution control and electrosynthesis, is hampered by kinetically sluggish electrode reactions. The mission of our research program is to discover and investigate selective, durable and cost-effective electrocatalysts and to integrate the catalyst structures with the electrode and cell design in order to develop high-performance electrochemical devices and processes. To accomplish our mission we deploy a multi-pronged approach combining fundamental experimental electrochemical and surface science studies of the electrocatalytic activity with theoretical insights into the catalytic activity, development of methods for nanostructured electrocatalyst deposition on electronically conductive 3D substrates and electrochemical cell and reactor engineering advancements.
