Abstract
We develop novel heterogeneous catalysts and catalytic processes with the aim to minimize the energy usage and negative impacts of such processes on environment while achieving high product yield and selectivity. We take a multi-disciplinary approach based on material science, reaction engineering, and in situ / operando spectroscopy to gain solid comprehension of the active sites and the transformation pathways. Currently our major attentions are given to the conversion of CO2 and CO2-derived chemicals into fuels and useful chemicals and also to the production of hydrogen, the important molecule for CO2 reduction. Also, powerful in situ / operando spectroscopic tools for studying solid materials and gas-solid and solid-liquid interfaces are being developed and applied to shed light on catalytic reaction mechanisms.
Topics addressed
- Catalytic CO2 conversion
- High-pressure CO2 hydrogenation to methanol
- Combined CO2 capture and reduction in one process
- Photocatalytic water splitting
