Combining Ti 3 C 2 and C 3 N 4 Synergy in Chitosan-Based Nanocomposites: Unprecedented Photocatalytic and Antibacterial activities

Abstract

Abstract The combined C3N4/Ti3C2 composite was created using a straightforward hydrothermal procedure, subsequently it was incorporated with chitosan and ultrasonically processed. The morphological characteristics, chemical composition, optical properties, and crystallographic information of the produced materials were ascertained using SEM-EDX, TEM, XRD, and UV-vis DRS. Under visible light exposure, the C3N4/Ti3C2@CS nanocomposite displayed significant photo-catalytic activity for the degradation of ofloxacin (OFX). Furthermore, the investigation explored the effect of various reaction parameters on the photocatalytic process. These criteria included the amount of catalyst used, the degree of pollutant in the system, and the inclusion of inorganic ions. Using the results of the tests, a possible charge transfer mechanism was suggested. Additionally, the antibacterial efficacy of the nanocomposites against microorganisms was greater. The improved photocatalytic activity of the nanocomposite was due to the synergistic effect of Ti3C2/C3N4 and CS, which results in efficient use of visible light and effective suppression of charge carrier recombination. Overall, this study reveals the possible use of C3N4/Ti3C2@CS in the photocatalytic removal of OFX from water.
