CNT/TiO2 nanocomposite for environmental remediation

Abstract

Abstract Nanomaterials and their composites have been proven to be effective materials for various energy and environmental applications. In this way, functionalized polymers and their nanocomposites (NCs) are receiving much attention due to their tunable physico-chemical characteristics, cost and ease of availability. As an environmental application, particularly the removal of toxic dyes, photocatalysis has been reported as an emerging technology. The literature survey shows that functionalized polymer nanocomposites (PNCs) as photocatalysts offer an extensive contribution towards the generation of clean, renewable, and practical forms of energy from light-based pollutant removal as environmental remediation. Here, the present concept provides a brief introduction to the field of photocatalysis and environmental remediation, followed by the application of functionalized PNCs. In this view, TiO2–NCs are reported to be effective photocatalytic materials. In the present study, CNT-doped TiO2 NCs samples have been prepared using the sol–gel method and their photocatalytic activity has been investigated through a dye degradation experiment. Compared to the present studies, here the CNT content taken is very low, and it is found to be effective for the dye degradation part of an environmental cleaning application.
