Abstract To enhance the performance of Mo-promoted Raney nickel catalyst, the loss by dissolution of molybdenum from Ni-Al-Mo ternary alloys, and effect of Mo-loss inhibition with adding sodium molybdate into initial caustic sodium solution during the Ni-Al-Mo ternary alloy spreading process were investigated. The catalytic performances in glucose hydrogenation of the catalysts prepared with or without the Mo-loss inhibition were studied contrastively，including recycle time, antitoxicity and catalytic activity in glucose hydrogenation of catalysts. Experimental results showed that the loss of molybdenum by dissolution from Ni-Al-Mo ternary alloy was obviously diminished with the Mo-loss inhibition during the alloy spreading process. It followed that the performances of the catalyst in glucose hydrogenation were improved, which including catalytic activity at first usage, recycle lifetime with critical dose, and anti-toxicity against saccharifying enzyme and sodium bisulfate.
