Functionalized 2D defect g-C 3 N 4 for artificial photosynthesis of H 2 O 2 and synchronizing tetracycline fluorescence detection and degradation

Artificial photosynthesis of H O is a clean production technology, which brings the synergistic effect to photodegradation of pollutants. Inspired by defect engineering, 2D defective carbon nitride (g-C N ) photocatalyst was obtained via potassium ion assisted synthesis. Defective g-C N is protonated and applied to photosynthesis of H O , H O concentration produced reached 477.7 μM, which was approximately 5.27 times that by pristine g-C N . Additionally, defective g-C N materials are borrowed to synchronizing tetracycline (TC) fluorescence detection and degradation, suggesting the catalyst existed bifunctional characteristics of TC detection and degradation. Meanwhile, metal impregnation engineering (molybdenum) was borrowed enhancing the electron-trapping ability in local region of defective g-C N , which takes advantages to the efficient degradation of TC. Furthermore, optical and electrical properties of photocatalysts were investigated in details by advanced material characterization testing. This work provides potential applications in the field of artificial photosynthesis and pollution degradation.
