Surface Plasmon Resonance Induced Photocatalysis in 2D/2D Graphene/g-C3N4 Heterostructure for Enhanced Degradation of Amine-Based Pharmaceuticals under Solar Light Illumination

Pharmaceuticals, especially amine-based pharmaceuticals, such as nizatidine and ranitidine, contaminate water resist treatment. Here, different amounts of graphene sheets are coupled with g-C3N4 nanosheets (wt% ratio 0.5, 1, 3 5 wt% graphene) to verify the effect surface plasmon resonance introduced material. The synthesized materials were systematically examined by advanced analytical techniques. prepared photocatalysts used for degradation pharmaceuticals (nizatidine ranitidine). results show that introducing only g-C3N4, absorption ability in visible near-infrared regions dramatically enhanced. range was 50 times higher when compared pure sample. These features suggest surfaces carbon nitride sheet covered nanosheet, which would effectively apply LSPR properties catalytic determinations. enhancement light composite confirmed PL analysis, showed greater inhibition electron-hole recombination process. XRD a decrease (002) plan due presence graphene, prevents further stacking layers. Accordingly, Gr/g-C3N4 samples exhibited an photocatalytic performance, specifically 5% sample, close 85% achieved within 20 min under solar irradiation. Therefore, applying pharmaceutical can be taken into consideration alternative method removal pollutants during treatment This attributed resonance-induced photocatalysis 2D/2D graphene/g-C3N4 heterostructure.
