Abstract
AbstractIn this manuscript role of MWCNTs on the photocatalytic response of zinc oxide (ZnO) semiconductor photocatalyst is reported. Developing a cheap, stable, and effective photo catalyst is necessary for remediation of persistent organic pollutants. To address this challenge, ZnO/MWCNT composites are fabricated via sonication technique with interfacial engineering for effective photocatalytic response. X‐ray diffraction spectra confirms hexagonal structure of ZnO/MWCNT composites with the average particle size distribution of 73–80 nm. FT‐IR spectra confirms bonding structure, however SEM images confirm the homogeneous distribution of MWCNTs in the ZnO system which acts as an effective adsorbent sites. The highest degradation (90%) of methylene blue (MB) dye on ZnO95MWCNT5 composite has been observed. It is expected that MWCNTs taking part to electron transfer facilitation in spatial separation and electron–hole pairs of ZnO during photo catalysis mechanism.
