	Ni-Mo supported on gamma-Al2O3 catalysts were synthesized to test its catalytic activity towards sucrose to 1,2-propanediol (1,2-PDO) conversion. The catalyst system was characterized using various physicochemical methods, including XRD, BET, py-FTIR, XPS, FE-SEM, HR-TEM and ICP. The metal combination of 8\%Ni-20\%Mo/gamma-Al2O3 is found to be effective in producing a good yield of 1,2-propanediol (similar to 74\%) under mild reaction conditions of 180 degrees C, 40 bar H-2 pressure and a run time of 4.5 h in a batch reaction. The activity of the active catalyst over various substrates such as cellulose, glucose, fructose and real-source biomass has also been investigated. XPS analysis of the active catalyst confirms the various oxidation states of the metals Ni and Mo in the active catalyst. The py-IR results show that the optimum Lewis to Bronsted acidic site ratio is responsible for the selective conversion of sucrose to 1,2-PDO. The presence of interparticle mesopores on gamma-Al2O3 helps in the high conversion of sucrose. Furthermore, the catalyst has been found reusable for four consecutive runs without any structural or morphological changes.</p>
