Abstract
The expeditious augmentation of industry and economics brought about the increment in pollution of the aquatic environment, which is a prerequisite to exploiting the new materials to remit pollution status. The construction of functional Zr-MOF (UiO-66) materials with layered MgAl-LDH in a hydrothermal synthesis strategy named UL3 (wt.%, UiO-66:MgAl-LDH=1:3) for highly efficient photodegradation diclofenac (DCF) was investigated in this study. The UL3/DCF photodegradation system under the premium react condition of 10 mg/L DCF, 0.1 g/L UL3 and 25 ℃ reached 100% mineralization of DCF within 5 min at pH 4. Quenching testing presented the dominant species in the photocatalytic was h+, and played synergetic roles during the degradation of DCF. Low metal ions leaching under 0.25 mg/L and co-existence substrates certified the high stability of UL3 and its good resistance to co-existing substances. This study identifies a viable photocatalyst system for water purification and solar energy utilization.
