Sol-gel Zr0.1Ce0.9O2 and Zr0.1(Ce0.75Pr0.25)O2 mixed oxides and coprecipitated pure ceria CeO2 displaying the fluorine type structure have been used as platinum or ruthenium catalysts’ supports for catalytic wet air oxidation (CWAO) of aqueous solution of acetic acid (78 mmol.L-1). These catalysts were prepared by conventional impregnation (5 wt-%) from platinum and ruthenium precursor salts or by exchange (~2 wt-%) in the case of ruthenium. A screening of catalysts in CWAO at 200°C under 2 MPa was performed and reveals that the best platinum catalyst is supported on pure ceria displaying large surface. For ruthenium catalysts, the highest conversion after 3 hours of reaction has been reached by the Ru/Zr-Ce-O system.

AbstractSingle-atom confined materials (SACMs) have been widely researched as catalysts in many fields within recent years. However, this class of materials may not only serve as a catalyst but also as a support material for certain reactions. Here we propose a general strategy to use SACMs as supports for tuning loaded noble metal (e.g., Ru) nanoparticles with enhanced catalytic activity. As a proof of concept, a nickel single-atom confined nitrogen-doped carbon nanotube (NCNT) superstructure is prepared as a support to load noble metal Ru for catalytic wet air oxidation of acetic acid. Improved catalytic activity with a mineralization rate of ~97.5% is achieved. Further, adsorption configurations based on DFT calculations also confirm our deduction that the introduction of single-atom Ni changes the intrinsic property of NCNTs and affects the loaded active Ru nanoparticles.
