Synthesis of silica supported ni and cu catalyst for carbon dioxide methanation reaction
منشور في 2019"…In addition, the used catalysts after the reaction were characterized using similar techniques to evaluate the effect of reaction conditions on active phase and SiO2 support. The 1%Ni on SiO2 catalyst shows good activity for CO2 conversion to CH4 till 450ºC, thereafter CH4 formation decreased and CO increased and remains the only product at 650ºC. …"
