Abstract	A series of La2O3 catalysts supported on activated carbon, with varying loadings of 2, 4, 6, 8, and 10 wt%, was synthesized via the impregnation method. The characterization of these samples was performed using powder X-ray diffraction (PXRD) and N2 adsorption-desorption isotherms. Carbon dioxide capture experiments were conducted using the fixed-bed method under room temperature and atmospheric pressure conditions. Notably, the catalyst with 10 wt% La2O3 incorporated activated carbon exhibited a high adsorption capacity of 119 μ.mol/g at 300C
