Relative capability analysis on carboxylate and imidazole based MOFs for PVP and PSS photo catalytic degradation in water

Carboxylate and Imidazole based metal organic framework (MOF) i.e., Zr-MOF (Zirconium metal-organic framework using ZrOCl2·8H2O and 1,4-benzenedicarboxylic acid, synthesised)) and ZIF-8 (Zinc Imidazole framework using Zn(NO3)2·6H2O and 2-methyl imidazole, commercially available) have been explored for photo catalytic degradation under certain experimental conditions. In order to quantify the effective photo degradation of MPs ( i.e., polyvinaypyrrolidone (PVP) and polystyrene sulfonate (PSS)) as well as their kinetics, UV–Vis spectrophotometry have been utilized. . Our experimental results confirmed that Zr-MOF has high photo catalytic degradation activity for PVP (82 %) and PSS (95 %) over ZIF-8 (PVP (65 %) and PSS (85 %) under two hours UV light exposure. Importantly, chemical intermediates produced during the degradation process have been identified, and their putative routes have been addressed. Our investigation reveals that Zr-MOF is a potential photo catalyst for PVP and PSS degradation in water.
