Improving Photocatalytic Antibacterial Activity from the Facile Fabrication ZnO Nano Particles with Metallic Hybrid-MWCNT

Abstract

In this study, we modified the MWCNT surface by using HNO3 to synthesize MWCNT-COOH and MWCNT-OH. Afterwards, ZnO particles were synthesized using a sol-gel reaction followed by the introduction of CNT, and CNT-ZnO with a modified surface was used to derive a synthesis towards a complex. The weight ratio was used as a split in the synthesis of MWCNT and ZnO to analyze the degree of synthesis, crystallizability, and surface image of the nano-particles and MWCNTs via XRD, Raman spectroscopy, and SEM. The SEM image confirmed that the ZnO nano-particles formed on the surface, and it is thus feasible to approximately identify the direction in which the ZnO was grown and at what size via XRD.
