Abstract:
Wet air oxidation (WAO) is an attractive technique for sewage sludge treatment. The WAO process and the factors influencing the process are examined in detail, together with the advantages and disadvantages. Catalytic wet air oxidation (CWAO) is emphasized because it can lower operational conditions, and the commonly-used and new homogeneous and heterogeneous catalysts are introduced. Homogeneous catalysts tend to be more appropriate for the CWAO treatment of sewage sludge, and Cu-based homogeneous catalysts such as CuSO4 are the most popular for industrial applications.

Abstract:
Catalytic wet peroxide oxidation (CWPO) of diluted aqueous solutions of phenol has been studied over a series of heterogeneous catalysts at 100°C under 1MPa air pressure. Several catalysts were prepared and tested including zeolitic materials exchanged with metallic ions such as Fe and Cu and different mixed oxides. Likewise, a Fe-TS- zeolite was synthesised by isomorphous substitution of Si atoms by Fe and Ti into the MFI zeolitic framework through hydrothermal synthesis of wetness-impregnated Fe2O3-TiO2-SiO2 xerogels. This material showed a complete phenol removal and TOC reduction of up to

Abstract:
Herein, we present a new heterogeneous catalyst active toward glucose to formic acid methyl ester oxidation. The catalyst was fabricated via electrostatic immobilization of the inorganic polyoxometalate HPA-5 catalyst H8[PMo7V5O40] onto the pore surface of amphiphilic block copolymer membranes prepared via non-solvent-induced phase separation (NIPS). The catalyst immobilization was achieved via wet impregnation due to strong coulombic interactions between protonated tertiary amino groups of the polar poly(2-(dimethylamino)ethyl methacrylate) block and the anionic catalyst.

Abstract:
This study investigated the decomposition of high strength p-nitrophenol (PNP) of 2,000 mg/l (3,400 mg of COD/1,250 mg of TOC) by catalytic wet air oxidation. Multi-component heterogeneous catalysts were used as catalysts for this purpose. The study results using a batch reactor showed that catalyst “D” (Mn-Ce-Zr 22.4 g plus CuSO4 1.0 g; Mn-Ce-Zr-Cu [CuSO4]) was more effective (56˜74%) than catalyst “A” (Mn-Ce-Zr 22.4 g) under the given conditions (O2 partial pressure of 1.0 MPa; temperature of 170˜190°C; 30 min of reaction time).

The structure and morphology of the core-shell microspheres were characterized by the XRD, IR spectroscopy, UV-Vis absorbance, and SEM. These microsphere materials can be used as heterogeneous catalysts with high activity and stability for catalytic wet air oxidation of pollutant dyes safranine T (ST) at room condition.

In this work, simple methods for the preparation of highly efficient heterogeneous nanocatalysts for the low-temperature oxidation of CO are described. The main advantages of the reaction are high yields. The catalysts based on oxides of copper and manganese supported on alumina monoliths were prepared by different methods: plasma corona discharge and wet impregnation. Structure and physical properties of catalysts were characterized by FT- -IR, XRD, TEM, EDX and TG/DTA. The results showed that the use of a plasma corona discharge at atmospheric pressure for the preparation of the catalysts re

Abstract:
Improving the kinetics of oxygen electrocatalysis is key to increasing the efficiency of hydrogen production from renewable sources, production of carbon-neutral fuels such as ethylene and rechargeable metal-air batteries1. Metal oxides exhibit state-of-the-art activity, but fundamental atomic-level insights into the reaction mechanism are often unknown. Particularly, various differences between materials, including the differences in active surface area, chemical state of the metal cations, fractional coverage of oxidized species and the range of ordered structure, renders it difficult to ide
