The Leddy Research Group investigates how physical manipulation of reaction conditions increases rates of electron transfer. Impacts of magnetic fields and of sound energy on electron transfer are evaluated through the synergy of fundamental investigations, modeling, and development of technologically relevant electrochemical energy systems such as batteries, fuel cells, and solar cells. Magnetoelectrocatalysis is especially effective where species are at high concentration and slow transport as for adsorbates. On Pt, CO is more readily oxidized; on p-Si generation of H2 is >5% photoefficient. Other projects include breath sensors and generation of NH3 by algae on electrodes.
