Molybdenum disulfide nanosheet/carbon aerogel hybrid material and preparation method therefor

The present invention belongs to the technical field of carbon aerogel, and particularly relate to a molybdenum disulfide nanosheet / carbon aerogel hybrid material and a preparation method therefor. The hybrid material is prepared by growing a molybdenum disulfide nanosheet in situ on a carbon aerogel particle with an irregular angular structure by using molybdenum salt and sulfosalt. The raw materials comprises the carbon aerogel, the molybdenum salt, and the sulfosalt. The preparation process comprises: carrying out a sol-gel method, carrying out freeze drying, and carrying out a high-temperature carbonized technology, thereby obtaining the carbon aerogel; obtaining the carbon airgel particle with the irregular angular structure by using a grinding or milling method; and and growing the molybdenum disulfide nanosheet in situ on the carbon aerogel particle by using a solvothermal method. The molybdenum disulfide nanosheet / carbon aerogel hybrid material prepared by the method disclosed by the invention has the characteristics that the molybdenum disulfide nanosheet has few layers ( only 3-6 layers), and is uniformly distributed on the carbon aerogel, so that the hybrid material can be used as an ideal catalyst material with high performance, an electrode material for new energy devices such as a lithium-ion battery or solar cells, and the like.

The invention relates to the field of mushroom cultivation technologies, in particular to a method for manufacturing edible mushroom solid liquefied strains. The method comprises the steps that first-level liquid strains are inoculated into a culture flask, and liquid spawn is obtained; a solid cultivation material is prepared, the liquid spawn is cultured in strain bottles, the cultivation temperature ranges from 22 DEG C to 25 DEG C, cultivation is conducted in a dark place, the cultivation humidity ranges from 50% to 60%, and the strains can grow full of the strain bottles after being cultured by 20-30 days; the strain bottles filled with the strains and having no infectious microbe are selected, and the strains are crushed in a pulverizer and inoculated into sterile water for direct production and inoculation. The method for manufacturing the edible mushroom solid liquefied strains has the advantages that the strain running speed is high and is 1/3 higher than that of solid strain running, 3-4 times of expansion inoculation are not needed, the strain contamination problem caused in the expansion inoculation process is solved, and time needed by expanding propagation is saved; growing points are more than the growing points of common liquid strains, strain running is uniform, the strain ages are consistent, produced mushrooms are orderly and good in quality, and fruit body yield can be improved by 20%-30%; sterile water is adopted for liquefying mycelia, molds and other infectious microbes can not grow, and contamination can be reduced by 5%-10%.

Silkworm excrement porous carbon MOFs composite material with high specific surface and preparation method and application thereof

The invention discloses a silkworm excrement porous carbon MOFs composite material with a high specific surface and a preparation method and application thereof. First, silkworm excrement and a ZnCl2 solution are mixed and swelled and then frozen and dried; then the frozen and dried silkworm excrement is subjected to an active pore expanding reaction, cleaned, centrifuged and dried to obtain a silkworm excrement-based multi-stage pore carbon material; next, a metal salt solution and the material are stirred and mixed and then centrifuged and dried; under the condition of plasma modification, oxygen is injected to form a high-dispersion metal oxide on the surface of the silkworm excrement-based multi-stage pore carbon material, then through a microwave irradiation method, MOFs are grown on the surface of the silkworm excrement-based carbon material with the high-dispersion metal oxide being a precursor, and finally the silkworm excrement porous carbon MOFs composite material with the high specific surface is obtained after suction filtration and drying. The material can be applied to pesticide slow controlled release. The obtained composite carbon material has the high specific surface and carboxyl groups, and can achieve the effects of high adsorption capacity and good slow controlled release.

Indium zinc sulfide nanosheet/tubular tin oxide heterojunction and preparation method thereof, and application of indium zinc sulfide nanosheet/tubular tin oxide heterojunction in degradation and removal of water pollutants

The invention discloses an indium zinc sulfide nanosheet/tubular tin oxide heterojunction and a preparation method thereof, and application of the indium zinc sulfide nanosheet/tubular tin oxide heterojunction in degradation and removal of water pollutants. According to the method, tin oxide nanotubes are prepared through an electrostatic spinning technology and a high-temperature calcination technology; and tin oxide serves as a substrate, and indium zinc sulfide nanosheets evenly grow on the surface of the substrate through an oil bath so as to construct the indium zinc sulfide nanosheet/tubular tin oxide heterojunction. Indium zinc sulfide is an important metal sulfide, has a band gap width of 2.6 to 2.7 eV and is a good semiconductor material, so the prepared indium zinc sulfide nanosheet/tubular tin oxide heterojunction has a large specific surface area, can provide more adsorption sites and catalytic active sites, effectively improves the separation efficiency of photo-induced electrons and holes, further improves the activity of a photocatalytic reaction, and can be better used for photocatalytic separation and degradation of water pollutants.
