Example Embodiment
[0030] Example 1
[0031] Weigh 0.05mmol of basic zinc carbonate, 0.015mmol of oxalic acid, 0.5mmol of 3-methyl-1,2,4-triazole, solvent of 5ml of water, stir evenly, add to autoclave, seal and put into oven In the process, heat the reaction at 200℃ for 24h, filter the reacted mixture, wash with water and methanol, and then dry to get the product, labeled Zn(ox) 0.5 (mtz)-1.
Example Embodiment
[0032] Example 2
[0033] Weigh 0.1mmol of zinc carbonate, 0.1mmol of oxalic acid, 0.5mmol of 3-methyl-1,2,4-triazole, 3ml of water and 3ml of n-butanol as the solvent, stir well, add to the autoclave, and seal it. Put it in an oven, heat it at 180℃ for 72h, filter the reacted mixture, wash with water and methanol, and then dry to get the product, labeled Zn(ox) 0.5 (mtz)-2.
Example Embodiment
[0034] Example 3
[0035] Weigh 0.2mmol of basic zinc carbonate, 0.2mmol of oxalic acid, 0.1mmol of 3-methyl-1,2,4-triazole, solvent of 5ml of water and 3ml of methanol, stir evenly, add to the autoclave, and seal Then put it in an oven, heat the reaction at 130℃ for 48h, filter the reacted mixture, wash with water and methanol, and then dry to get the product, labeled Zn(ox) 0.5 (mtz)-3.
