“…The overall oxidation activity of catalyst C at 190 8C decreases during reaction, which might be explained by development of strongly adsorbed species on the surface [9,10]. These may be eliminated at higher temperature (!200 8C).…”

“…The Ru catalyst with a high ratio of zero-valent state showed the highest activity for the CWAO of acetic acid, and thus more than 95% of TOC removal was attained at 230 C and 10 bar of oxygen. Wang et al [92] reported the activity order of Ru catalysts on different supports for the CWAO of acetic acid at 200 • C and 4 MPa as follows:…”

“…On the other hand, wet air oxidation (WAO) is a method of oxidizing dissolvable or suspended organic compounds as well as reducible inorganic compounds with oxygen or air at high-temperature and high-pressure conditions [2]. However, the application of WAO is limited because of its severe operation conditions and rather costly investment [3][4][5]. Catalytic wet hydrogen peroxide oxidation (CWHPO) has been developed to decompose highconcentration effluents, as well as poisonous, detrimental and hardly degradable wastewaters [6,7].…”

p-Hydroxybenzoic acid (p-HBZ) degradation was achieved using catalytic wet hydrogen peroxide oxidation over Fe/TiO 2 and Ru-Fe/TiO 2 under mild conditions. The results showed that 71 % of p-HBZ conversion was obtained after 10 min of reaction over the 0.5Ru-3Fe/ TiO 2 catalyst calcined under oxygen. The influence of the H 2 O 2 /p-HBZ molar ratio (5:1, 10:1 and 15:1), reaction temperature (25, 40 and 60°C), Fe loading (1, 2 and 3 wt%) and thermal treatment was studied. Characterization studies were performed by X-ray diffraction, N 2 physisorption at 77 K, H 2 -TPR and elemental analysis, showing that close interaction between Ru and iron oxide species is necessary to obtain active and stable catalysts. Graphical Abstract 0.5Ru-3Fe/TiO 2 C catalyst shows a high activity for the degradation of p-HBZ at 60°C by CWHPO in the presence of H 2 O 2 . The system could be considered as a Fenton-like reaction due to the generation of radicals from H 2 O 2 as well as the presence of iron sites on the catalyst.
