Abstract

The invention discloses a micro-nano structure zinc oxide-carbon composite pellet and a preparation method thereof. The micro-nano structure zinc oxide-carbon composite pellet is obtained by hybridization compounding of zinc oxide and carbon to obtain a solid pellet having the diameter of 6-12 micrometers, wherein vertical nanosheets having the length of 700-900 nanometers, the height of 700-900 nanometers and the thickness of 15 to 25 nanometers are formed on surfaces of the solid pellet and are connected with each other into a nest; a mole ratio of zinc oxide to carbon is (60-70%): (30-40%); zinc oxide has a hexagonal structure; and carbon comprises amorphous carbon and graphitized carbon and a weight ratio of the amorphous carbon to the graphitized carbon is (85-95%): (5-15%). The preparation method comprises the following steps of dissolving zinc acetate dihydrate, urea, sodium citrate dihydrate and glucose in water to obtain a mixed solution, carrying out hydrothermal treatment on the mixed solution to obtain a reaction solution, orderly carrying out solid-liquid separation, washing and drying to obtain an intermediate product, putting the intermediate product in an inert gas atmosphere, and carrying out annealing to obtain the micro-nano structure zinc oxide-carbon composite pellet. The micro-nano structure zinc oxide-carbon composite pellet can be widely used for fields of catalysis, adsorption and photoelectricity.

Description

technical field

[0001] The invention relates to a composite ball and a preparation method thereof, in particular to a micronano structure zinc oxide-carbon composite ball and a preparation method thereof. Background technique

[0002] Zinc oxide is an excellent semiconductor material, which is widely used in environmental governance and optoelectronic devices; for example, its excellent photocatalytic performance can degrade toxic organic pollutants into carbon dioxide and water under the irradiation of ultraviolet light or even sunlight. Utilizing its excellent piezoelectric performance, it can be made into a nanogenerator device, and its excellent photoelectric conversion performance can make it widely used in solar cells. Carbon materials with excellent electrical conductivity and adsorption properties are widely used in the fields of optoelectronics and hydrogen storage. Based on the above two points, recently, people have made unremitting efforts to obtain zinc oxide-c...
