TL;DR: In this paper, the authors investigated the Catalytic Wet Air Oxidation (CWAO) process for ammonium ions removal from wastewater. And the greatest interest of CWAO compared to the classical biological one, is that the selectivity towards molecular nitrogen is much higher (>90%).

TL;DR: In this paper, catalytic wet oxidation reactions of aqueous phenol over unpromoted, base and noble-metal promoted MnO2/CeO2 catalysts were carried out under mild conditions (80-130°C, 0.5MPa O2) in a batch slurry reactor.

TL;DR: In this article, the catalytic wet air oxidation (WAO) of p -coumaric acid (PCA) has been investigated over Fe- and Zn-promoted ceria catalysts.
Abstract: The catalytic wet air oxidation (WAO) of p -coumaric acid (PCA) has been investigated over Fe- and Zn-promoted ceria catalysts. The catalysts have been prepared by the coprecipitation method and have been characterized by X-ray diffraction (XRD), BET surface area, SEM–EDX and temperature programmed reduction (TPR). The oxidation reaction was carried out in a batch reactor under an air pressure of 2 MPa and in the temperature range 353–403 K. Fe-CeO 2 catalysts, with 20–50 mol% of iron, were found more effective than the unpromoted and Zn-promoted ceria catalysts. On the basis of characterization data, it has been suggested that the higher activity of the Fe-promoted catalysts is related to the modification of the structural and redox properties of the ceria oxide catalyst on addition of iron.

TL;DR: In this article, the degradation behaviors of an azo dye, cationic red X-GRL, by three clean advanced oxidation processes: wet oxidation (WO), electrochemical oxidation (EO), and wet electrochemical oxidization (WEO) were compared.

TL;DR: In this article, the dependence of oxidation rate on O2 concentration is approximately first order at low oxygen concentrations, with a saturation in the rate above 15 mol% O2, but significantly degrades the rate at higher concentrations.
