Embodiment 1
[0053] 1.16g zirconium chloride and 0.83g terephthalic acid (H 2 BDC) was dissolved in 150 mL of N,N-dimethylformamide, 1.65 mL of 37% hydrochloric acid was added, and magnetically stirred for 30 min. The solution was then transferred to a reaction vessel, a 200 mL Teflon-lined stainless steel autoclave, and reacted in an oven at 120 °C for 24 hours. After cooling to room temperature, the mother liquor was decanted. The product was washed repeatedly with dimethylformamide and methanol. Afterwards, the product was dried overnight at 120°C. The resulting material is then ground into powder form. The powder was placed in a crucible and placed in a muffle furnace for 30 min at 200°C in an air atmosphere to obtain the final UiO-66 modified sample. Its denitrification reaction efficiency can reach close to 95% at 170°C.
Embodiment 2
[0055] 1.16g zirconium chloride and 0.83g terephthalic acid (H 2 BDC) was dissolved in 150 mL N, N-dimethylformamide, 0.92 g formic acid was added, and magnetically stirred for 30 min. The solution was then transferred to a reaction vessel, a 200 mL Teflon-lined stainless steel autoclave, and reacted in an oven at 120 °C for 24 hours. After cooling to room temperature, the mother liquor was decanted. The product was washed repeatedly with dimethylformamide and methanol. Afterwards, the product was dried overnight at 120°C. The resulting material is then ground into powder form. Put the powder in a crucible and put it into a muffle furnace for calcination at 200 °C to obtain the final UiO-66 modified sample. Its denitrification reaction efficiency can reach nearly 85% at 200°C.
Embodiment 3
[0057] 1.16g zirconium chloride and 0.83g terephthalic acid (H 2 BDC) was dissolved in 150 mL N, N-dimethylformamide, 1.20 g acetic acid was added, and magnetically stirred for 30 min. The solution was then transferred to a reaction vessel, a 200 mL Teflon-lined stainless steel autoclave, and reacted in an oven at 120 °C for 24 hours. After cooling to room temperature, the mother liquor was decanted. The product was washed repeatedly with dimethylformamide and methanol. Afterwards, the product was dried overnight at 120°C. The resulting material is then ground into powder form. The powder was placed in a crucible and placed in a muffle furnace for 30 min at 200°C in an air atmosphere to obtain the final UiO-66 modified sample. Its denitration reaction efficiency can reach nearly 80% at 200°C.
