Description of the research topic:

Billions of dollars are investigated into information industry. Its less known, that similar budget is used for planning catalysis and industrial catalytic processes. The former trial-and-error method can be exchange with new techniques using in-situ methods for molecular level understanding under reaction conditions as well as controlled nanotechnology. In our research, mono and bimetallic nanoparticles with controlled average sizes were synthesized and anchored them on different 3D mesoporous oxide materials prepared by the soft and hard template (replica) method. HRTEM-ED-EDX, SEM-EDX, DRIFTS, XRD, BET, H2-TPR, NH3-TPD etc. can be used for characterizations. Catalytic tests were performed in a flow reactor in the gas phase connected to a HP GC-FID-TCD. Tuning the size of the particles as well as the oxide/metal interfaces high activity and selectivity processes are favorable. NAP-XPS as well as DRIFTS techniques helped for molecular level understanding of the processes for future catalysts design. I will show plenty of results on the field of nanocatalysis and CO2 activation reactions.
