The present invention provides one kind of nanometer MoO3 stick and its preparation process. The laminated nanometer MoO3 stick in orthorhombic system has length 1-10 microns, 3-9 laminated MoO3 layers, thickness 50-200 nm and width 60-120 nm. The preparation process includes dissolving molybdenum oxide or molybdate in hydrogen peroxide solution via intense stirring for 30-50 hr to form sol, transferring the sol into stainless steel reaction tank with PTFE lining, hydrothermal treatment at 150-180 deg.c for 4-6 days, naturally cooling to room temperature to obtain hydrothermal product, anhydrous ethyl alcohol washing and water washing, and drying. The preparation process is simple, high in reproducibility, controllable, and environment friendly. The prepared nanometer MoO3 stick has high surface activity and may be filmed via brushing or spraying and prepared into electrochemical and optical devices directly or after being mixed with other superfine powder.
