Abstract

The invention discloses a preparation method of a hypha / nanoparticle composite sphere material. The preparation method is characterized by comprising steps as follows: preparing a culture medium; adding 4-20 ml of a nanoparticle aqueous solution containing 1-10 mg of nanoparticles per milliliter to the sterilized liquid culture medium, evenly mixing the mixture, inoculating the mixture with strains, culturing the mixture for 48-96 h under conditions that the temperature is 15-35 DEG C and rotating oscillation is performed at the speed of 80-200 r / min to form a hypha / nanoparticle composite sphere material, performing filtration to remove a liquid, soaking solids, namely, hypha / nanoparticle composite spheres, with a sodium hydroxide aqueous solution for 12 h, washing the spheres with deionized water until the spheres are neutral, and then performing freeze-drying to prepare the hypha / nanoparticle composite sphere material. The composite sphere material prepared with the method is applicable to fields of industrial catalysis, wastewater treatment, biomedicine and the like and has the characteristics of low cost, high activity, easiness in recovery and the like.

Description

technical field [0001] The invention belongs to the preparation of organic-inorganic nanocomposite materials, and relates to a preparation method of a mycelium / nanoparticle composite ball material. The mycelium / nanoparticle composite ball material prepared by the invention is mainly suitable for the fields of industrial catalysis, waste water treatment, biological medicine and the like. Background technique [0002] Nanomaterials have been valued in many disciplines such as physics, chemistry, materials, and biology due to their many excellent characteristics compared with traditional materials. However, due to the small particle size of previous nanomaterials, the recycling technology is difficult. This leads to an increase in the cost of use, which limits its large-scale application. In order to solve this problem, it must be composited to solve the problem of nanomaterial recycling by loading the nanoparticles into the carrier. [0003] In recent years, with the develop...
