Abstract: We have evaluated the efficient of degradation of lignin by an photoelectrochemical process. Using a Ti/Ru0.1Sn0.6Ti0.3O2 electrode, a quartz reaction device and an artificial ultraviolet light, decoloration ratios higher than 70%, and reductions of 51% and 83% in TOC and total phenol products, respectively, were observed for a reaction time of 6 h. Comparing these values with the sum of the decoloration ratios (or TOC and total phenol reductions) obtained by separate measuring of electrochemical and photochemical procedures, a significant synergetic effect between these two processes was observed. Furthermore, the degradation capacity of the photoelectrochemical process increases as the SnO2 content is increased.
