Heterogeneous photocatalysis and photoelectrocatalysis have beenconsidered as oxidation technologies to abate unselectively noxious species. Thisarticle focuses instead on the utilization of these methods for selective syntheses oforganic molecules. Some promising reactions have been reported in the presenceof various TiO2 samples and the important role played by the amorphous phasehas been discussed. The low solubility of most of the organic compounds in waterlimits the utilization of photocatalysis. Dimethyl carbonate has been proposed asan alternative green organic solvent. The recovery of the products by couplingphotocatalysis with pervaporation membrane technology seems to be a solutionfor future industrial applications. As far as photoelectrocatalysis is concerned, adecrease in recombination of the photogenerated pairs occurs, enhancing the rateof the oxidation reactions and the quantum yield. Another benefit is to avoidreaction(s) between the intermediates and the substrate, as anodic and cathodicreactions take place in different places.
