摘要: In this research, new catalyst with high industrial impact is developed, which can catalyze the conversion of CO2 to methane through methanation reaction. A series of catalysts based on nickel oxide were prepared using wetness impregnation technique and ageing, followed by calcination at 400 ℃. Rh/Ni (30 : 70)/Al2O3 catalyst was revealed as the most potential catalyst based on the results of catalytic activity measurement monitored by Fourier Transform Infrared Spectroscopy (FTIR) and Gas Chromatography (GC). The results showed 90.1% CO2 conversion and 70.8% yield at 400 ℃.
