We request 7 days on TOSCA to carry out inelastic neutron scattering study of two novel multifunctional catalysts (Ru/Nb2O5Hx and Pd/Nb2O5Hx) for the efficient cleavage of C-O bond of phenol molecules for biomass (lignin) conversion and processing. This proposed study will investigate the vibrational spectroscopy of the catalysts, the absorption of the guest phenol molecules on catalysts and any possible reaction intermediates. In particular, this study aims to reveal the roles of residual surface ¿OH groups in the binding to the guest molecules and in the catalytic reactions. These recently-discovered multifunctional catalysts exhibit extremely high selectivity and activity for the hydrogenolysis of lignin and its derivatives, such as guaiacol, to aromatic hydrocarbons with tremendous potential market value.
