novel complexes, [CoL(H2O)] (1), [ZnL(H2O)] (2), [Ni(HL)2(H2O)2]·2H2O (3), and [CdL(H2O)]·H2O (4) (L = 5-aminoisophthalic
acid), were successfully synthesized by the reaction of transition
metal salts and 5-aminoisophthalic acid at hydrothermal conditions.
The four complexes were characterized by element analysis, infrared
spectra, UV–vis spectra, powder X-ray diffraction analysis,
and thermogravimetric analysis. X-ray single-crystal diffraction analysis
showed that the four complexes were 3D network structures and contained
pores with sizes of 7.05 to 14.67 Å. In addition, we investigated
the photodegradation ability of the four complexes for phenol solution
under UV irradiation. The results showed that the four complexes had
a different degree of degradation ability to phenol solution. At the
same time, we found that the degradation process was in accordance
with the pseudo-second-order dynamics model, that is, the rate of
degradation is controlled by the extra-particle process such as surface
adsorption. Moreover, we further confirmed by high-performance liquid
chromatography that the complexes are indeed a significant ability
to degrade phenol.
