Title:
METHOD OF PREPARING MOLYBDATE COMPLEX HOLLOW MICROSPHERES AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/109830
Kind Code:
A1
Abstract:
Disclosed is a method of preparing molybdate complex hollow microspheres, including steps of: (1) dissolving 1-4 mmol of MCl2 in 20 ml of water to obtain a solution A and dissolving 1-4 mmol of molybdic acid in 20 ml of water to obtain a solution B, followed by mixing the solution A and the solution B, in which M is Co, Ni, or Cu; (2) dissolving 10-40 mmol of urea in 40 ml of water, adding the mixed solution of step (1) and stirring uniformly; (3) placing the mixed solution of step (2) into a reaction vessel and reacting at 120-160 °C for 6-12 hours; (4) suction filtrating and water washing, followed by drying in a vacuum oven at 40-60 °C; (5) calcination at 350-500 °C for 2-4 hours in a Muffle furnace. The prepared molybdate complex hollow microspheres have higher effective contact area and porosity. The process is simple, and the raw materials are cheap and easy to obtain. The preparation process does not require a surfactant as a structure directing agent for morphology control. The synthesized molybdate complex hollow microspheres exhibit superior catalytic activity in catalyzing the hydrolysis of ammonia borane for producing hydrogen.
