Embodiment 1
[0028] ① Pour sodium hydroxide (0.003 mol, 0.1200 g) into 10 ml of absolute ethanol, and then ultrasonically in an ultrasonic cleaner for a period of time until all sodium hydroxide is dissolved in absolute ethanol (wherein NaOH can be prepared by KOH, LiOH 、Na 2 CO 3 , NaHCO 3 and other alkaline substances instead);
[0029] ②Add o-mercaptobenzoic acid (0.003 mol, 0.4626 g) into the solution in ①, and stir on a constant temperature magnetic stirrer until completely dissolved;
[0030] ③ CoCl 2 ▪6H 2 O (0.0015 mol, 0.3565 g) was completely dissolved in 5 ml of deionized water, and then the solution was slowly dropped into the above solution with a dropper, and continued to stir for half an hour (the cobalt raw material can also be CoSO 4 ▪6H 2 O, Co(NO 3 ) 2 ▪6H 2 O. CoC 4 h 6 o 4 ▪4H 2 O and other commonly used cobalt salts are acceptable);
[0031] ④ Pour the stirred solution into a 30 ml polytetrafluoroethylene-lined stainless steel reaction kettle, and react ...
Embodiment 2-5
[0034] The reaction temperature in step ④ was set to 120°C, 150°C, 180°C, and 200°C respectively, and the other reaction conditions were the same, and a black powder product was prepared.
[0035] The following materials are mainly characterized by products prepared at a temperature of 120 °C, at which the yield of the complex is the highest.
