[0033] A kind of preparation method of nearly spherical nickel molybdate / subphthalocyanine composite material, concrete steps are as follows:
[0034] 1. The synthesis process of subphthalocyanine needs to be carried out under anhydrous and oxygen-free conditions, so nitrogen is generally used for protection. Such as Figure 9 , the synthesis method is the solvent method: under the protection of an inert gas, the reaction raw materials and the solvent are added, and the solvent 1,2-dichlorobenzene is first anhydrous and oxygen-free, that is, it is distilled, cooled to room temperature, and set aside. Subsequently, under the protection of nitrogen, 1.050 g of phthalonitrile and 5.50 mL of BCl were added to the flask 3heptane solution. Heat the mixture to 150° C., keep the temperature constant for 35 minutes, distill off the heptane, continue to heat the mixture to 180° C., keep the constant temperature for 3.5 hours, cool to room temperature, and distill off the solvent. The...

[0047] 1. The synthesis process of subphthalocyanine needs to be carried out under anhydrous and oxygen-free conditions, so nitrogen is generally used for protection. The synthesis method is a solvent method: under the protection of an inert gas, the reaction raw materials and a solvent are added, and the solvent 1,2-dichlorobenzene is first subjected to anhydrous and oxygen-free treatment, that is, it is distilled, cooled to room temperature, and set aside. Subsequently, under the protection of nitrogen, 1.050 g of phthalonitrile and 5.50 mL of BCl were added to the flask 3 heptane solution. Heat the mixture to 150° C., keep the temperature constant for 35 minutes, distill off the heptane, continue to heat the mixture to 180° C., keep the constant temperature for 3.5 hours, cool to room temperature, and distill off the solvent. The dried product was washed with methanol until the methanol was colorless, and then extracted with chloroform. Finally, the solvent was evaporated...
