Preparing and characterizing an optimal supported ceria catalyst for the catalytic wet air oxidation of phenol

Catalytic wet air oxidation of phenol over CeO2-TiO2 catalyst in the batch reactor and the packed-bed reactor

“…Among the applications, it shows the most important use in the catalysis fields. CeO 2 is used as both the support and catalyst in the CWAO of organic compounds [23][24][25][26][27]. However, the thermostability of pure CeO 2 under hightemperature conditions is poor.…”

Cerium Oxide Based Catalysts for Wet Air Oxidation of Bisphenol A

“…However, the additional separation step of the homogeneous catalysts has made them less interesting and the development of active heterogeneous catalysts has received more attention in the research area of CWAO. Numerous heterogeneous catalysts such as activated carbon, CeO 2 , TiO 2 , MnO 2 , ZrO 2 and their mixed oxides [12][13][14][15][16][17][18] have been tested in the CWAO of phenol, acetic acid and industrial effluents. Moreover, noble metals (Pt, Ru, Pd) supported on mixed oxides have been found to be the most efficient catalysts in CWAO of different effluents than pure metal oxides [19][20][21].…”

Effect of CeO2 doping on catalytic activity of Fe2O3/γ-Al2O3 catalyst for catalytic wet peroxide oxidation of azo dyes

“…Many investigators have been trying to improve the catalytic activity and stability of heterogeneous oxidation catalysts to enhance the efficiency of CWO [10][11][12], and cerium oxide and CeO 2 -containing materials have been studied as catalysts, structural and electronic promoters used for heterogeneous catalysis over past years. It has been shown that cerium oxide promotes oxygen storage and release to enhance oxygen mobility, and forms surface and bulk vacancies to improve the catalyst redox properties of the composite oxide when it is associated with transitional metal oxides [13][14][15].…”
