C3N4 Anchored ZIF 8 Composites: Photo-regenerable, high capacity sorbents as adsorptive photocatalysts for the effective removal of tetracycline from water

Abstract

Materials combining the abilities of adsorption and photocatalysis provide a facile solution for pollutant disposal as secondary remediation processes are avoided. Herein, we report a simple strategy for the development of C3N4 anchored ZIF-8 microcrystals as sheathed architectures for the highly efficient adsorption and sun light induced photocatalytic degradation of tetracycline from solutions. Adsorption capacity, as high as, 420 mg/g of adsorbent was realized for a composition containing 60:40 wt% of C3N4 and ZIF. Subsequently, the adsorbed tetracycline was degraded to over 96% in 1 h of sunlight exposure. The effects of pH and adsorbate concentration are studied and valid adsorption and degradation kinetic models are arrived at. The bifunctional composite thus developed offer a photo-regenerable adsorbent for the effective removal of an emerging hazardous contaminant.
