Abstract

Abstract: In this study, the oxidative cross-linking copolymerization method was used to create an ultra-efficient hybrid nanocomposite for the photocatalytic degradation of Rhodamine-B (RhB). First, a novel hybrid nanocomposite-based cross-linked PANI was created in the presence of hybrid nano-fillers mixed graphene oxide and single-walled carbon nanotubes (GO-OXS) doped CuO and coated with chitosan abbreviated as C –P (ANI-co-PPD)/Cs-GO-OXS/CuO NCs. Different characterization techniques were used to characterize and confirm the chemical structure of the synthesized material. The results showed that there was no significant weight loss for both C –P (ANI-co-PPD) and the C –P (ANI-co-PPD)/Cs-GO-OXS/CuO NCs, which can be attributed to their high thermal stability. The photocatalytic degradation of RhB, which was carried out using this novel hybrid nanocomposite, was successful. It showed that nanocomposite is efficient at RhB dye adsorption in aqueous solutions. Approximately 94% degradation of 2.0 × 10 −5 M of RhB dye was achieved in 130 min at pH 6.0 using 10 mg of C –P (ANI-co-PPD)/Cs-GO-OXS/CuO NCs under UV radiation. The C –P (ANI-co-PPD)/Cs-GO-OXS/CuO NCs nanocomposite is an effective adsorbent for removing hazardous dye from wastewater that is both convenient and reusable.
