Abstract
The present disclosure belongs to the technical field of sewage treatment, and relates to a preparation method and use of a cobalt nanoparticle/boron nitride composite. The preparation method includes the following steps: dissolving 2-methylimidazole and boric acid in deionized water, and stirring to obtain a solution A; dissolving Co(NO)·6HO and Zn(NO)·6HO in deionized water, and conducting ultrasonic dispersion to obtain a solution B; transferring the solution B into the solution A, and stirring to form a clear and transparent solution; transferring the clear and transparent solution into a container lined with Teflon, and conducting a reaction; subjecting an obtained product to cooling, filtration, washing, and drying sequentially to obtain a precursor of the composite; and conducting roasting on the precursor in an ammonia gas atmosphere to obtain the cobalt nanoparticle/boron nitride composite with a spherical superstructure.
