Abstract

The invention discloses a method for synthesizing nano-zinc oxide by a micro-emulsion carbon black adsorption precipitation method. The method for synthesizing nano-zinc oxide comprises the following steps: using zinc oxide, carbon black and ammonia water as raw materials, dripping a cyclohexane micro-emulsion system prepared by ammonia solution to a cyclohexane micro-emulsion system consisting of zinc chloride and carbon black, performing precipitation reaction after mixing and stirring at normal temperature and performing vacuum distillation, multiple washing, drying, grinding and calcination on the precipitate adsorbed by carbon black, and obtaining high thermal-stability nano-zinc oxide. The method is mild in reaction conditions, high in yield, and capable of preventing ultrafine zinc oxide from agglomerating and sintering to some extent; and the obtained products have the characteristics of high crystallinity, large specific surface area, small particle size, and good photo-catalytic performance.

Description

technical field

[0001] The invention relates to a method for synthesizing nano-zinc oxide by microemulsion carbon black adsorption and precipitation method, belonging to the technical field of nano-material preparation. Background technique

[0002] Nano zinc oxide is a new type of high-function fine inorganic product. Nanoscale ZnO has surface effect, quantum size effect and small size effect, etc. Compared with ordinary ZnO, it shows many special properties, such as non-toxicity, non-migration, fluorescence, piezoelectricity, conductivity, etc., and in Transparent in the visible light range, high reflectivity in the infrared band and other characteristics. Therefore, using the photosensitive theory of zinc oxide semiconductors, nano-zinc oxide can be used as a highly efficient photocatalyst for degrading organic pollutants in wastewater and purifying the environment.

[0003] In order to improve the photocatalytic activity of ZnO, ZnO must have small particle size, large...
