%X Incipient wetness impregnation (IWI) method was applied to prepared 10Cu/Al2O3 whereas MLa-doped 10Cu/Al2O3 (Mwt= 1, 2, 3, 4 and 5) were synthesized by employing sequential IWI technique. The prepared catalysts were evaluated from ethanol CO2 reforming (ECR) at 1023 K and stoichiometric feed ratio. Average crystallite size of CuO particle is reduced with La-promoter addition probably caused by lanthana dilution effect that prevent agglomeration from occurring within CuO particles. H2 reduction process produce complete CuO reduction and constant signal is appearing beyond 525 K suggests that the catalysts were completely reduced beyond that temperature. 3La catalyst identified as optimal promoter loading based on reactant conversions. C2H5OH and CO2 conversions were achieved on 3La loading is 87.6 and 55.1, respectively. Carbon was identified on catalyst surface based on X-ray diffraction (XRD) and scanning electron microscopy (SEM). © 2019 Author(s).
