Embodiment 1
[0033] (1) ZnCl 2 Stir and react with ChCl in a constant temperature oil bath at 100°C for 1 hour at a molar ratio of 2:1, and obtain uniform, colorless and transparent ZnCl after cooling 2 / ChCl deep eutectic solvent;
[0034] (2) adding in the deep eutectic solvent that step (1) makes is 0.5% Ce(NO 3 ) 3 ·6H 2 O was stirred until it was completely dissolved to obtain a light yellow mixed solution. Add distilled water with a volume ratio of 1:1 to the deep eutectic solvent, and then adjust the pH value of the solution to 8 with 25% ammonia water, and obtain a light yellow solution after ultrasonic mixing for 30 minutes. emulsion;
[0035] (3) Transfer the light yellow emulsion prepared in step (2) to a polytetrafluoro-lined hydrothermal synthesis reactor, then place the reactor in an oven at 120°C for 12 hours of hydrothermal reaction, after the reaction The reaction solution was cooled and centrifuged to obtain a light yellow solid, and the light yellow solid was washed...
Embodiment 2
[0039] (1) ZnBr 2 Stir and react with ChCl in a constant temperature oil bath at 100°C for 1 hour at a molar ratio of 2:1, and obtain uniform, colorless and transparent ZnCl after cooling 2 / ChCl deep eutectic solvent;
[0040] (2) adding in the deep eutectic solvent that step (1) makes is 1% Ce(CH 3 COO) 3 ·5H 2 O was stirred until it was completely dissolved to obtain a light yellow mixed solution. Add distilled water with a volume ratio of 2:1 to the deep eutectic solvent, and then adjust the pH value of the solution to 9 with 25% ammonia water, and obtain a light yellow solution after ultrasonic mixing for 30 minutes. emulsion;
[0041] (3) Transfer the light yellow emulsion prepared in step (2) to a PTFE-lined hydrothermal synthesis reactor, then place the reactor in an oven at 140°C for 11 hours of hydrothermal reaction, after the reaction The reaction solution was cooled and centrifuged to obtain a light yellow solid, which was alternately washed with ethanol and d...
Embodiment 3
[0045] (1) ZnCl 2 Stir and react with ChCl in a constant temperature oil bath at 100°C for 1 hour at a molar ratio of 2:1, and obtain uniform, colorless and transparent ZnCl after cooling 2 / ChCl deep eutectic solvent;
[0046] (2) adding in the deep eutectic solvent that step (1) makes is 2% Ce(NO 3 ) 3 ·6H 2 O was stirred until it was completely dissolved to obtain a light yellow mixed solution. Add distilled water with a volume ratio of 2:1 to the deep eutectic solvent, and then adjust the pH value of the solution to 10 with 25% ammonia water, and obtain a light yellow solution after ultrasonic mixing for 30 minutes. emulsion;
[0047] (3) Transfer the light yellow emulsion prepared in step (2) to a PTFE-lined hydrothermal synthesis reactor, then place the reactor in an oven at 160°C for 10 hours of hydrothermal reaction, after the reaction The reaction solution was cooled and centrifuged to obtain a light yellow solid, and the light yellow solid was washed alternately...
