| description | © 2017 The Royal Society of Chemistry. 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 C 3 N 4 anchored ZIF-8 microcrystals as sheathed architectures for the highly efficient adsorption and sunlight induced photocatalytic degradation of tetracycline from solution. An adsorption capacity as high as 420 mg g -1 of adsorbent was realized for a composition containing 60:40 wt% of C 3 N 4 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 offers a photo-regenerable adsorbent for the effective removal of an emerging hazardous contaminant. |
