Toxic environmental drug nimesulide detection and degradation using the Bi-functional vanadium and phosphorous doped graphitic carbon nitride nanosheets

Abstract

In this manuscript “Feed two birds with one seed” strategy was followed to study the electrochemical ability and photocatalytic Degradation of pharmaceutical effluent nimesulide (NIM) drugs. Heterogeneous solid-direct Z-scheme catalysts experienced many efforts in generating new materials to tackle environmental issues by exhibiting appropriate catalysts. Currently, graphitic carbon nitride (gCN) with its unique characteristics has attracted tremendous kindness among researchers due to its excellent potential for utilization as a bi-functional catalyst. In this research, the part of surface morphological engineering and band gap evolution in heterojunction solid-direct Z-scheme formation of vanadium and phosphorous doped gCN (V/P-gCN (VP)) will be considered. The proposed material is prepared by thermal decomposition and the analytical analysis was utilized to study the physio-chemical characteristics. These newly developed strategies are more useful to enhance the electrocatalytic and photocatalytic activity of gCN. In addition, specific information on the application of gCN-based catalysts in the bi-functional simultaneous process will be obtained in different reactions. The analytical parameters of the proposed sensor were adequate, with higher recovery values, and the detection limits and quantification range are 0.2 – 80 μM and 3 nM, respectively for the detection of NIM. Photocatalytic Degradation of NIM targets harmful pollutants obtained 98% within a short treatment time under visible light illumination. In addition, the possible degradation pathways of NIM drugs were studied using GC-MS analysis, which exhibited the degradation of NIM molecules with small fragments. These dual-functional approaches could provide sustainable and efficient strategies for both electro and photocatalyst to rectify environmental issues.
