An efficient adsorbent and catalyst: AgNPs fabricated in triaizne based conducting polymer for the reduction of 4-nitrophenol

摘要

4-Nitrophenol (4-NP) is a highly toxic organic pollutant exists in several industries wastewater and harmful to the human health as well as to the ecosystem. The fast removal and coast effective reduction of 4-NP is great challenge, to solve the environmental and human health issues. In the present study, I have fabricated novel AgNPs into porous conducting polymer matrix without using any external stabilizer and reducing agents, because triaizne based conducting polymer behaves as a stabilizer and self-reducing agents. The FTIR and XPS analyses revealed that the polymer matrix not only contains aromatic moiety, but also have several imine groups. XRD results support the formation of AgNPs in to the polymer and show the FCC crystalline structure. The SEM and TEM results revealed that the spherical AgNPs are well dispersed in the polymer matrix and the average diameter of AgNPs was found to be 30 nm. The fabricated nano composite is a high prose materials and show excellent adsorption capacity and catalytic activity towards the reduction of 4-NP to 4-AP at room temperature. The catalytic activity factor was observed to be 1.668 s(-1) g(-1) and support outstanding catalytic activity of AgNPs@CP. This approach can be used to fabricate other catalysts and advance materials for potential applications in environmental chemistry.
