Embodiment 1
[0043] 1. Add 100ml of deionized water to the acid-resistant reactor; weigh 0.04mol of analytically pure ammonium heptamolybdate, dissolve it in deionized water, and obtain 0.4mol / l ammonium heptamolybdate clarified liquid;
[0044] 2. Prepare 100ml of 50% acetic acid solution, add 20ml of hydrogen peroxide to obtain acidifying precipitant;
[0045] 3. Heat the reaction kettle in a water bath to 60°C; at the same time, slowly add the acidifying precipitant to the ammonium heptamolybdate solution dropwise at a rate of 5ml / min, while stirring until the pH value of the solution reaches 3.5;
[0046] 4. Filter the reaction solution to obtain a yellow-white precipitate;
[0047] 5. Put the yellow-white precipitate in an oven and dry it at 100°C to obtain massive molybdenum oxide;
[0048] 6. Pulverize the massive molybdenum oxide and pass through a 40-mesh sieve to obtain coarse molybdenum oxide powder;
