“…In agreement with the results for phenol oxidation, among different metals (Ru, Pt, Rh, Ir, Cu, Mn, Ni and Co), Ru supported on carbon exhibited superior activity towards carboxylic acid decomposition without metal leaching after 3 h of use [125]. Not surprisingly, partial oxidation of the carbon supports occurred during the oxidation of diverse refractory carboxylic acids, the temperature of reaction being as high as 200°C [125,128].…”

“…Not surprisingly, partial oxidation of the carbon supports occurred during the oxidation of diverse refractory carboxylic acids, the temperature of reaction being as high as 200°C [125,128]. Pt also showed a good oxidation potential, but sems to be completely inactive at temperatures below 160°C [71,130].…”

“…In all studies listed in table 3, the accumulation of refractory acetic acid occurred during the oxidation leading to an undesired corrosive reaction medium with pH values close to 3. Carbon supports and noble metal catalysts are known to be stable at low pH values and effectively, severe leaching was only reported for supported Cu [120,121] and Mn [124,125] catalysts. It can be concluded that the use of carbon as support gave good results in CWAO of phenolic compounds.…”

“…During the last years considerable research efforts were focused on reducing unwanted catalyst deactivation. Stable supported catalysts with high activity towards oxidation of organic pollutants have been successfully synthesised and tested in the oxidation of phenol [66][67][68][69][70][71][72][73][74][75][76][77][78]. These new catalysts remain, however, relatively expensive materials and the search for cheap, active and stable CWAO catalysts continues.…”

-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.
