Abstract

The invention provides a synthesis method of a basic zinc sulfate scale microsphere, and belongs to the technical field of the preparation of inorganic functional materials. The synthesis method comprises the followings steps: dispersing zinc vitriol into ethanol, promoting zinc vitriol to be dispersed in an ethanol medium in a microsphere way through stirring action, and then adding triethylamineinto a system. The basic zinc sulfate scale microsphere is prepared through the reaction of triethylamine and zinc vitriol in a hydrothermal condition. The formed microsphere comprises a plurality ofbasic zinc sulfate scales tangent to the surface of the microsphere, and a gap formed by the scales in different directions is formed inside the microsphere. The synthesis method is simple, good in reproducibility, and mild in synthesis condition. The invention provides a strategy for synthesizing an inorganic functional compound scale microsphere, and the formed basic zinc sulfate scale microsphere is expected to have a wide application prospect because of the unique structure.

Description

technical field [0001] The invention relates to a method for synthesizing basic zinc sulfate flake microspheres, which belongs to the technical field of preparation of inorganic functional materials. Background technique [0002] Basic zinc sulfate is a zinc salt compound belonging to the triclinic system. It is one of the main components of the metal zinc passivation protective film. The composite coating composed of metal zinc can effectively prevent the corrosion of the steel plate. The application of basic zinc sulfate also involves the fields of chemical synthesis and aquaculture. For example, the modification of basic zinc sulfate to Ru catalyst can effectively inhibit the conversion of cyclohexene to cyclohexane through the stagnant film formed on its surface, thereby improving the The selectivity and yield of benzene hydrogenation to cyclohexene; used as a precursor to synthesize zinc oxide film with good fluorescence properties; used as an additive of trace element ...
