brief introduction

The increasing demand for high activity and selectivity products needs new technologies and understanding of heterogeneous catalysis. The former trial-and-error method can be exchanged with new techniques using in-situ methods for molecular level understanding under reaction conditions as well as controlled nanotechnology. These techniques may be exploited in CO2 activation as well as other green methods. In our research, mono and bimetallic nanoparticles with controlled average sizes were synthesized and anchored them on different 3D mesoporous ceramic oxide materials. Beside the basic characterization methods (HRTEM-ED-EDX, SEM-EDX, DRIFTS, XRD, BET, H2-TPR, NH3-TPD) in situ Raman, XRD, XPS, 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 towards a new sight into green catalysis. Based on the atomic level understanding, industrial application was approached in a form of cheap, noble metal-free catalysts pressed into proper forms used for pilot-scale exhaust system upgrading of fuel engines or wooden-heated ovens will be introduced as well as results on high pressure CO2 activation towards C5+ fuel products.
