Abstract

The invention discloses a method for preparing mycelium / nanoparticle composite spherical material, which is characterized in that it comprises: preparing a culture medium; adding 1 to 10 milligrams of nanoparticle to the sterilized liquid culture medium in a concentration of 1 to 10 milligrams per milliliter of solution 4-20 ml of aqueous solution of nanoparticles, mixed evenly, inoculated with strains, and cultured for 48-96 hours at a temperature of 15-35°C and 80-200 rpm rotating and oscillating to form mycelium / nanoparticle composite ball materials , filtered to remove the liquid, and the solid matter, that is, the mycelia / nanoparticle composite ball was soaked in sodium hydroxide aqueous solution for 12 hours, washed with deionized water until neutral, and then freeze-dried to obtain the mycelium / nanoparticle composite ball material . The composite ball material prepared by the invention is suitable for industrial catalysis, waste water treatment, biomedicine and other fields, and has the characteristics of low cost, high activity, easy recycling and the like.

Description

technical field [0001] The invention belongs to the preparation of organic-inorganic nanocomposite materials, and relates to a method for preparing hyphae / nanoparticle composite ball materials. The hyphae / nanoparticle composite ball material prepared by the invention is mainly applicable to the fields of industrial catalysis, waste water treatment, biomedicine and the like. Background technique [0002] Due to its many excellent properties compared with traditional materials, nanomaterials have been paid attention to in physics, chemistry, materials, biology and other disciplines. However, due to the small size of nanomaterials in the past, recycling technology is difficult, thus 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 compounded, and the problem of nanomaterial recycling can be solved by loading nanoparticles to the carrier. [0003] In recent years, with the development of industri...
