RSC Adv

October 2024

Faculty of Chemistry, Ho Chi Minh City University of Science, Vietnam National University, Ho Chi Minh City 227 Nguyen Van Cu Street, Ward 4, District 5 Ho Chi Minh City 70000 Vietnam

This study aimed to address the issue of rapid electron-hole recombination in photocatalysis by exploiting multi-phase TiO decorated on multiwalled carbon nanotubes (MWCNTs) to improve the photocatalytic degradation of dyes. A simple and eco-friendly one-pot method was utilized to create the TiO/MWCNT nanostructure using glucose as both a structure-directing agent and a carbon source without requiring any prior covalent or non-covalent functionalization of the MWCNTs at 160 °C. Furthermore, it was found that the average width of the nanocomposites changed from 20 ± 1 and 42 ± 2 nm to 56 ± 3 nm, corresponding to MWCNT contents of 1.
