The invention relates to a graphene airgel-supported nano-metal or metal alloy catalyst and a preparation method thereof, which belongs to the field of nano-material application and catalytic technology, and is characterized in that: graphene oxide and metal compounds are used as precursors, and a continuous reduction method is adopted , to obtain small-sized nano-metal and nano-metal alloy particles loaded three-dimensional porous graphene airgel catalyst. In the catalyst, the types of nano-metals and nano-metal alloys are selected from: Pt, Au, Ag, Pd, Ru, Rh, Pb, Fe, Co, Ni, Ir, Cu, etc.; the types and proportions can be arbitrarily matched. The size of the nanoparticles is about 2-6 nm, and they are evenly distributed on the graphene sheet. At the same time, graphene is assembled into a three-dimensional porous airgel structure with an average pore size of 1-2 microns, which can have a high specific surface area, high electron transport and mass transport rate, and prevent the agglomeration of graphene and nanoparticles. The composite material has excellent catalytic performance, and the components of the catalyst can be selected according to different needs.

The invention provides a technology for extracting Germacrone from Rhododendron thymifolium Maxim leaves with a freezing method and belongs to the technical field of extraction and separation of effective active ingredients of plants. The technology comprises steps as follows: the Rhododendron thymifolium Maxim leaves are smashed to form powder, and volatile oil is extracted with a vapor distillation method firstly; the volatile oil is dehydrated with anhydrous sodium sulfate and placed in a low-temperature environment for freezing, crystals are separated out and filtered, the crystals are dissolved with ethyl alcohol and recrystallized after being washed with ethyl alcohol, filtering and washing are performed again, and high-purity Germacrone is obtained. A high performance liquid chromatography analyzer determines that the purity of Germacrone extracted and separated with the technology is 95%-98%, the yield can be up to 0.20%-0.50%. The technology is simple, short in process, low in power consumption and cost and high in yield and product purity and requires simple equipment; water and ethyl alcohol are taken as solvents, so that the technology is environment-friendly and clean and has little pollution; industrial production can be realized.
