Embodiment 1
[0041]Follow the steps in the technical plan. First, 5 g of anhydrous GeCl 4 Dissolve in 44mL tetrahydrofuran to form a transparent solution with a molar concentration of 0.5mol / L. A mixed solution of 15mL octane, 1.8mL pentanol, 0.5mL aqueous formaldehyde and 1.25g cetyltrimethylammonium bromide was mixed with 5ml octane, 0.7mL oleylamine, 0.5mL of 0.5mol / L GeCl 4 The THF solution and the mixed solution of the three substances were mixed into a beaker and mixed and stirred under a 78HW-3 constant temperature magnetic stirrer to form a transparent microemulsion; the obtained beaker with the transparent microemulsion was placed in an ultrasonic cleaner and ultrasonically oscillated for 3 minutes Afterwards, the reaction was stopped, and the white turbid solution obtained by the reaction was centrifuged at 10000r / min for 15 minutes to obtain a solid product, which was dispersed and washed again with absolute ethanol, and centrifuged again, and the pure white germanium dioxide ...
