Novel multi-metallic catalysts for biomass conversion Ilaha Hasanova and Cristina Giordano Queen Mary University London, Mile End Road, London, E1 4NS
The success of technologies for conversion of biomass into valuable chemicals and biofuels is dependent on development of sustainable catalyst with high performance. One of the most important reactions related to biomass valorization is the hydrodeoxygenation (HDO). Among different promising catalysts, Ni and Fe have attracted special attention due to their abundance, low price and aptitude to adsorb H 2 and disrupt H-H bond. At the same time, Fe also possesses prominent adsorption capacity for O-containing molecules [1] . Thus, we have designed novel heterogenous catalysts containing Ni and Fe sites for conversion of biomass model compounds into value-added chemicals and biofuels. Transition metal, carbide and bimetallic nanoparticles were synthesized via eco-friendly urea-glass route. The influence of several reaction parameters (such as, metals ratio, urea:metal ratio, temperature, heating rate) on final composition and morphology of final product was also investigated. Products were characterized by X-ray Diffraction analysis, Transmission and Scanning Electron Microscopy and Energy Dispersive X-ray analysis, which confirmed the expected chemical nature of the systems, and small nanoparticles size.
