Objectif
Heterogeneous photocatalysis offers a lot of possibilities to find the appropiate environmental friendly solutions for the problems affecting our society among them the energy´s problems. Researchers are still looking for a new routes to synthetize solid photocatalysts which will be able to transform more efficiently solar energy into chemical energy. In many developing countries, biomass is still a major energy source. The Roadmap for Biomass Technologies, authored by 26 leading experts from academia, industry, and government agencies, has predicted a gradual shift back to a carbohydrate-based economy. Biomass and biofuels appear to hold the key for satisfying the basic needs of our societies for the sustainable production of liquid fuels and chemicals without compromising the needs of future generations. In this research, I will work on novel routes of preparation of metal-nanostructured photocatalysts. The novelity of these methods of synthesis are based on the anchoring of metals such as Fe, Cr, Ti, Pd, Pt by the application of ultrasonic and photo-ultrasonic irradiation to obtain metal-nanostructured materials with specific properties. USY-Zeolite with high Si/Al molar ratio and Fumed-SiO2 will be used as carriers. Those carriers have interesting textural properties which are very helpful in hetero-photocatalysis and have not been yet broadly investigated. I will provide a complete characterization of all synthesized photocatalysts using a wide range of physico-chemical techniques (XRD, XPS, UV-vis, chemisorption, among others) and explore the potencial application in the specific example of selective conversion of glucose/xylose (model compounds of lignocellulosic biomass structure) to high value chemicals.
