Mixed-node A-Cu-BTC and porous carbon based oxides derived from A-Cu-BTC as low temperature NO-CO catalyst

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 AO(x)/CuOy/C were obtained by a heat treatment of A-Cu-BTC under N-2 atmosphere, which were found to be more effective as lower temperature catalysts. These characterizations of mixed-node A-Cu-BTC and AO(x)/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.
