Various loadings of Ni (5-20wt%) supported on CuO-Al

mixed oxide catalysts has been explored for the low temperature steam reforming of bio-ethanol. It has been found that 10wt%Ni/CuO-Al

catalyst showed relatively high ethanol conversion as well as selectivity towards H

(∼74%) compared to other catalysts. The better performance of the 10wt%Ni/CuO-Al

is explained based on the physico-chemical characteristics of the catalysts determined by BET – surface area, X-ray diffraction analysis (XRD), temperature programmed reduction (TPR), O

pulse chemisorption, X-ray photoelectron spectroscopy (XPS), Fourier transformed infrared spectroscopy (FT-IR) and differential thermal/thermo gravimetric (DT/TGA) analyses.
