This invention discloses a hydrothermal method for preparing Bi₂MoO₆ / tourmaline functional composite materials, belonging to the field of functional materials technology. The preparation method of the Bi₂MoO₆ / tourmaline functional composite material of this invention is as follows: Molybdenum source and bismuth source are added to deionized water to prepare solution A and solution B, respectively; tourmaline powder is added to deionized water to prepare suspension C; solution B is added dropwise to solution A and stirred, then suspension C is added and stirred again to obtain mixture D; sodium hydroxide solution is added dropwise to mixture D to prepare mixture E; mixture E is transferred to a hydrothermal reactor, sealed for reaction, and cooled to obtain hydrothermal product F; hydrothermal product F is separated by suction filtration and washed to obtain wet filter cake G; wet filter cake G is dried to obtain solid H; solid H is ground to obtain the final product. The Bi₂MoO₆ / tourmaline functional composite material prepared by this invention has high negative oxygen ion generation efficiency and environmental adaptability, and can still maintain high-efficiency release capacity in low humidity or light-free environments.

This invention discloses an ionizing emissive for iron isotope analysis and its preparation and testing methods. The ionizing emissive comprises a silicon nanoparticle suspension, a phosphoric acid solution, and an aluminum nitrate solution, wherein the phosphoric acid solution and aluminum nitrate solution are used as emissive excipients. In the iron isotope analysis testing method, the silicon nanoparticle suspension is used as a high-sensitivity emissive to enhance the ionization efficiency of the iron sample. Simultaneously, the phosphoric acid solution and aluminum nitrate solution assist ionization, and a high-purity rhenium filament is used as the sample carrier to test trace amounts of iron isotopes. The filament ionization temperature is 1350–1450℃. This invention has the advantages of high sensitivity, simple operation, and low cost. Compared with the traditional thermal ionization mass spectrometry method which requires 4000–50000 ng of sample, this invention only requires 400–4000 ng to obtain good iron isotope testing accuracy (<0.02%, RSE), significantly reducing the amount of iron sample used while improving testing sensitivity.
