“…Equation (2) was used to determine the chemical oxygen demand (COD), i.e., the amount of oxygen required to completely oxidize the organic products. A similar equation was used by Santos et al (2002b) to determine the COD of the intermediate products during the catalytic oxidation of phenol in the aqueous phase.…”

-The Catalytic Wet Air Oxidation (CWAO) of phenol using copper oxide catalysts supported by γ-Al 2 O 3 , TiO 2 , and pillared clay was evaluated to identify which of these catalysts was the most appropriate for this reaction. The CuO/PILC, CuO/γ-Al 2 O 3 and CuO/TiO 2 catalysts were the most successful at removing phenol and resulted in more than 96% conversion. Among these catalysts, CuO/γ-Al 2 O 3 produced the largest amount of CO 2 , the lowest amount of intermediate products and the lowest amount of copper leaching. These results showed that the CuO/γ-Al 2 O 3 catalyst was the best for the end of the reaction. However, the methods used in this study did not allow us to identify the most appropriate reaction time (or catalyst). An alternative approach for this problem was to quantify the costs for each reaction time. Using this approach, the CuO/γ-Al 2 O 3 catalyst was the most economically favorable catalyst when it was used during the first hour of the reaction.

“…Based on the pioneer work of Devlin and Harris [207] on phenol WAO, detailed oxidation pathways of pure phenol [64,65,79,119,122,125,160,[208][209][210][211], phenolic compounds [64,124,212] and carboxylic acids [72,122,125,127,130] were experimentally assessed for different catalysts including activated carbon [79,160] and activated carbon supported Ru, Pt, Pd metals [119,122,125,127,130,211]. The distribution of partial oxidation products obtained in phenol CWAO essentially involved the same species as those found by Devlin and Harris.…”

“…Oxidation reactions of a similar molecule, phenol were found to yield ring opening products like maleic, formic, acetic, oxalic, malonic, succinic, and fumaric acids. These occurred not only on the electrode, but also in the liquid or solution phase [44].…”

In this study a Photoelectrochemical Cell (PEC) constructed with inexpensive materials photodegraded selected organic compounds present in model waste waters, with the concomitant production of electrical current. Organic substrates dissolved in salt water included formic acid, 2-propanol, 1,2-dihydroxybenzene and ascorbic acid. Significant degradation of ascorbic acid was achieved when the cell was illuminated with a household 60 W tungsten light bulb, although better results were achieved with UV sources. Degradation of all the compounds was found to occur by zero order kinetics, and the PEC was shown not to work appreciably in dark conditions. Using a conventional light bulb, a formic acid PEC produced a power density of 19.1 ± 2 mW m -2 . When exposed to natural daylight, a power density of 31.5 ± 2 mW m -2 was achieved. There is considerable scope for scale up of this device for exterior use.
