▎ 摘 要
NOVELTY - Preparing iron molybdate superfine nano particles involves (1) dissolving ferric sulfate, sodium molybdate and polyvinylpyrrolidone in a mixed solution of deionized water and glycol, and marking the obtained mixed solution as solution A, (2) ultrasonically dispersing 1-3 pts. wt. graphene oxide in 40-60 pts. wt. deionized water, adding graphene oxide dispersion solution to the solution A and recording as solution B, (3) transferring the solution B to the reaction kettle, reacting at 260-360℃ for 10-15 hours, and collecting the reaction product, and (4) calcining the reaction products under the air condition to obtain iron-metal oxide superfine nanoparticles. USE - The method is useful for preparing iron molybdate superfine nano particles, which is used as a cathode material for lithium-ion batteries (claimed). Can also be used in electrochemical, optical and catalytic properties, photoluminescence, microwave transmission, optical fiber, magnetic material, humidity sensor, electrode material and catalysis. ADVANTAGE - The method: is simple and convenient, strong repeatability, and is good for industrial large-scale production; provides iron-molybdate superfine nano particles with good crystallinity, high purity, and good charging and discharging reversibility and cycle stability; and utilizes easily available raw materials of industrial grade products. The device is simple. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a iron molybdate superfine nano particles.
