| Abstract: In the same reaction conditions, the isotactic metal-doped[CoxCd1-x(pypymba)2]n (0 ≤ x ≤ 1) (compounds 1~5) were synthesized based on ligand (Hpypymba=4-((3-(pyrazin-2-yl)-1H-pyrazol-1-yl)-methyl)benzoic acid) and a transition metal ion (Co(Ⅱ), Cd(Ⅱ)). The structure and morphology were characterized by powder X-ray diffraction (PXRD) and UV-visible scanning. The obtained MOFs were used as a catalyst carrier to carry Ag ions to carry out a reduction reaction of 4-nitrophenol. The results showed that the Compound 1 which contained Co2+ was the better catalyst carrier. As the proportion of Cd2+ in compounds increased, the reaction rate decreased, and even the reaction has a certain inhibitory effect. The maximum loading of the MOFs for Ag was 47%(w/w), and 96% of the catalytic efficiency after 4 cycles. |
