Catalysis for Energy Conversion and Emission Control
My main research fields are catalysis for energy conversion and emission control. By developing new catalytic materials and catalyst-based techniques to convert greenhouse gases and emissions, I want to reduce the impact of such compounds on the climate and the environment. My research is performed within the Competence Centre for Catalysis, KCK, which is an interdisciplinary research centre at Chalmers. Particularly the study of kinetics and reaction mechanisms for the catalytic reduction of nitrogen oxides, catalytic oxidation of hydrocarbons at low temperatures, and surface processes during conversion of CO2 and methane to valuable platform chemicals is of major interest.
The research combines modern techniques, particularly in situ techniques, and methods within catalysis and nanoscience to relate catalytic properties as activity, selectivity and stability with physiochemical properties of the catalytic material studied.
An especially important issue in the research is the use of well-controlled perturbations of the reactant composition, to improve the performance of the catalyst, and to identify the surface processes that control the reaction considered. My vision is to contribute to a sustainable transport, energy and environmental system with new catalyst-based techniques.
