A series of modified Cu- ZnO-Al2O3 based catalysts have been synthesized by the co-precipitation method at different pH. These catalysts were evaluated for the synthesis of methanol in the temperature range 220 to 260 oC at 35 bar with space velocity of 3,000 h-1 and feed molar ratios of H2/CO=2. The catalysts have been characterized by XRD, SEM, elemental analysis, surface area and porosity measurements and TPR. It was found that the catalyst synthesized at pH 7 was most active with a CO conversion of 35.7% and a methanol selectivity of 75% and this can be used as an efficient catalyst for the methanol synthesis
