• A series of mixed-node A-Cu-BTC has been prepared through solvothermal method.
• A-Cu-BTC has been first investigated in selective catalytic reduction denitration with CO.
• AOx/CuOy/C has been obtained under nitrogen atmosphere, which showed a outstanding performance in elective catalytic reduction denitration with CO.
• These catalysts should be a promising substitution of noble metal ternary catalysts using for vehicles.
Mixed-node A-Cu-BTC (A = Sr, La, Ce, Al) was obtained through hydrothermal method, which was already successfully investigated that could be applied as a catalyst in selective catalytic reduction of NO with CO (CO-SCR). Mixed-node A atoms were proved through elemental analysis method using an Energy Dispersive Spectrometer. In addition, CuOy/C and AOx/CuOy/C were obtained by a heat treatment of A-Cu-BTC under N2 atmosphere, which were found to be more effective as lower temperature catalysts. These characterizations of mixed-node A-Cu-BTC and AOx/CuOy/C were performed by scanning electron microscopy with energy dispersive X-ray analysis, X-ray powder diffraction, infrared spectroscopy, thermo-gravimetric analysis and specific surface area using the BET method. The possible reaction mechanism about CO-SCR is discussed. These results provide that mixed-node MOFs and oxides prepared from mixed-node MOFs both have a promising application for CO-SCR.
Series of mixed-node A-Cu-BTC catalysts were obtained through solvothermal method, investigating that could be as promising selective catalytic reduction with NO by CO. AOx/CuOy/C were also obtained and investigated in CO–NO reaction, which were successfully applied in a lower catalytic temperature.Figure optionsDownload as PowerPoint slide
