Photo-electro-chemical properties of TiO2 mediated by the enzyme glucose oxidase

The photo-oxidation of 1,2-propandiol on TiO2/GO is regioselective in that (i) partial oxidation to hydroxyacetone is observed and (ii) no mineralization (full combustion to CO2) of the substrate occurs. These facts are of particular interest in the field of studies concerning the design of new photocatalytic systems with enhanced activity and controllable oxidative power.
