Research activity focuses on the investigation of the surface reactivity of nano-oxides and oxide based nanocomposites. The main objective of this research is to develop active materials to be used in heterogeneous catalysis. Particular attention is devoted to the green processes with the aim of developing oxide based materials for a sustainable development. Example of the applications:
- New Advanced Electrodes for Intermediate Temperature Solid Oxide Fuel Cells (SOFCs);
- PGMs free catalysts for advanced applications (Three Way Catalysts, sensors, as an example);
- Development of sustainable catalysts for clean hydrogen production (alcohols steam reforming and oxidative steam reforming, dry reforming).
The research activity mainly concerns the design, synthesis and characterization of oxide based nano-materials and nano-composites (perovskites, transition metal oxides, …). Nano-materials, synthesized with different procedures, are characterized with a multi-technique approach and their reactivity is investigated. By means of the interaction with probe molecules, the active (acidic/basic and red/ox) sites are investigated and the influence of their distribution and strength is considered with respect to the activity and selectivity in oxidation and reduction reactions (oxidation of alcohols, carbon monoxide and hydrocarbons, reduction of nitrogen oxides, …). Objectives:1) investigate the reaction mechanisms; 2) correlate the observed reactivity with the strength and surface distribution of active sites; 3) evaluate the influence of doping, synthesis parameters, etc. on the activity and selectivity.
Both the catalysts and the preparation procedures are selected taking into consideration the economic and environmental sustainability.
The reaction process is also investigated and optimized also with ad hoc developed reactors; the main interest is toward sustainable processes:
- CCS (Carbon Capture and Storage)
- CO2 conversion
- Emissions and Pollution control
- Sustainable hydrogen production
