GRANADA-RAMIREZ, O.L. et al. Oxidación de glicerol en fase acuosa con platino soportado en óxido de titanio. Superf. vacío [online]. 2016, vol.29, n.1, pp.9-13.  Epub 23-Out-2020. ISSN 1665-3521.

In this work, the synthesis of platinum catalyst supported on titanium oxide (Pt/TiO2) for the removal of glycerol is described, as a contaminant present in aqueous effluents, by catalytic wet oxidation reaction. Synthesis of titanium oxide (TiO2) is by the sol-gel method. The Pt is deposited on the TiO2 using the technique of incipient wetness impregnation in ratio 0.5 and 1.0 wt%, morphological and structural properties of both the support and the catalyst by conventional characterization techniques are studied. Tests of catalyst activity in the glycerol removal are performed in a batch reactor, slurry type, and the remaining glycerol concentration by UV-vis is determined. Activity results show a removal of 90 % glycerol at a temperature of 150 °C, with the catalyst Pt/TiO2 1.0 wt%.
