Electrocatalysis

Do you remember that the price of crude oil went up to ~120 USD / barrel in 2008, and the price of food, petrol and almost everything (except for my bank interest) increased? Why should we allow the price of some hydrocarbons, which can change drastically over a few weeks, affect so quickly the quality of our lives? An urgent scientific goal for the 21st century is to develop a sustainable and environmentally friendly energy economy. To contribute to this objective, we aim to understand and develop efficient and robust materials to catalyze several energy conversion reactions. Systems of interest include electrorereduction of CO2 to methane and methanol, fuel cell reactions (methanol oxidation, ORR), and water splitting (HER and OER). The macroscopic aspects of these reactions are generally understood. However, we still do not comprehend them at the molecular level. This prevents us from building better systems with the required efficiency and sustainability to be economically viable. Our strategy to address this issue: Obtain fundamental knowledge of these catalytic processes. We will elucidate the mechanistic and structural aspects of these reactions with high spatial and temporal resolutions. We will establish the fundamental relationships between the structure/composition of the catalysts with their activities. This knowledge will then be exploited to design and synthesize systems with improved functionality. We aim to synthesize catalysts from earth abundant materials, so that they can be used on a wide scale. Develop prototype devices, for example, an integrated CO2 electroreduction cell powered by solar energy to produce methane fuel. The success of our research will be a critical step towards establishing an energy industry based on renewable feedstocks such as H2O and CO2. It means that we can move away from fossil fuels for our energy needs. Our success will also be a big boost to environmental protection.
