Abstract
Catalytic Wet Peroxide Oxidation (CWPO) relies on the oxidation of organic pollutants in water under mild operating conditions (T=25-130 ºC, P=1-5 atm) using hydrogen peroxide as oxidant. It represents an emerging technology whose main challenge, currently limiting its industrial application, is the development of catalysts capable of combining a good activity along with an adequate stability for long- term use and high efficiency of H2 O2 consumption. This paper summarizes some of the results obtained by the Chemical Engineering Group of Universidad Autónoma de Madrid (UAM) on the application of that technique with carbon-based catalysts using phenol as target compound. The catalysts tested cover from metals supported on activated carbon to bare carbon materials including carbon blacks and graphites. Cyclic voltammetry has been successfully used to evaluate the activity of those materials in CWPO
