Paper-pulp and food industries supplies a significant quantity of residues that constitute a renewable source of lignocellulosic material. Non-edible biomass can replace edible biomass feedstock and constitutes a sustainable source of carbon for the production of fuels and chemicals without forcing extensive changes in land and water use [1].  In photocatalytic oxidation processes organic wastes can be converted into valuable compounds or completely being mineralized.  In the present piece of work, titania supported on silica and zeolite has been prepared by a modified ultrasound-assisted sol-gel method [2]. Based on the chemical composition of lignocellulosic material, glucose as monomer of cellulose and phenol (water pollutant) as lignin-representative molecule have been chosen to serve as model compounds in liquid phase photocatalytic reaction tests: selective photocatalytic oxidation of glucose and phenol photocatalytic degradation.  The prepared nanophotocatalysts have been precisely characterized by different techniques: XRD, N2physisorption, UV-vis and ICP-MS.  Photocatalytic oxidation of phenol is currently a promising method for mineralization (energy release) of such pollutants. Moreover, the partial photo-oxidation of sugars can lead to the production of high-value chemicals.References:[1] J.C. Serrano-Ruiz et al., Chem. Soc. Rev.40 (2011) 5266.[2] J. C.
