Abstract

The invention discloses a preparation method of a shape-controlled zinc hydroxide fluoride nano material and application thereof in a photocatalysis field. The zinc hydroxide fluoride nano material obtained by the preparation method is controllable in shape. The preparation method comprises the following specific steps: dissolving zinc nitrate and ammonium fluoride in water or an alcoholic solution, then adding sodium hydroxide, stirring to adjust pH until the solution is slightly alkaline, finally transferring into a polytetrafluoroethylene lining for sealing, after heating in water bath, washing, drying and grinding to obtain a finished product. The nano material is simple in synthetic method and low in cost; the prepared zinc hydroxide fluoride (ZnOHF) nano structure is controllable in shape; and the nano material has an obvious capacity for photodegrading pollutants, so that the nano material has potential application in photocatalytic degradation.

Description

technical field [0001] The invention relates to the technical field of photocatalysis of nanomaterials, in particular to a method for preparing a zinc fluoride hydroxide nanomaterial with controllable morphology and its application in the field of photocatalysis. Background technique [0002] With the development of industry, the water resources we use are increasingly polluted. Therefore, the removal of toxic and harmful chemicals such as pesticides and organic dyes in water has become a hot spot in the field of environmental protection. However, most of the current water pollution treatment methods are aimed at For pollutants with large discharge and high concentration, there is no very effective method for the purification of low-concentration and difficult-to-transform organic pollutants in water. However, the photocatalytic degradation technology developed in recent years provides a solution to this problem. better way. [0003] As an important Zn-based composite mat...
