The application discloses a metal-loaded vertical array light lanthanum fluoride-based nanosheet catalytic membrane and a preparation method, and belongs to the technical field of catalytic membrane materials. The catalytic membrane comprises a base film, a light lanthanum fluoride-based nanosheet array in-situ vertically grown on the surface of the base film, and metal active species loaded in pores. The catalytic membrane prepared by the application has a uniform distribution and a topological structure nanosheet vertical light lanthanum fluoride-based nanosheet array layer grown on the surface, and simultaneously loads metal active species catalysts in the array layer. The catalytic membrane exhibits high catalytic activity and stability in the field of heterogeneous Fenton catalysis, photocatalysis, and photo-Fenton synergistic catalytic degradation of organic pollutants in water bodies, and the catalytic membrane is easy to separate from wastewater and can be recycled.

The application discloses a wettable powder and a preparation method thereof, and belongs to the technical field of microbial preparations. The powder is prepared by compounding one or more kinds of microbial spores of Trichoderma harzianum, Penicillium bilaiae, Aspergillus niger and Paecilomyces lilacinus as core raw materials, and a wetting agent and a carrier. The special wetting agent can effectively improve the self-wetting effect of various spore powders, realizes quick wetting of the powder in water, and no floating and caking. The carrier can flexibly dilute the spore raw material, and is suitable for the production requirements of products with different viable bacterial contents, and the product has strong adaptability. The preparation process is simple, the product has excellent wetting performance and stable properties, can be effectively used for agricultural soil improvement and crop soil-borne disease prevention and control, and has extremely high agricultural application value.
