Synthesized rGO/f-MWCNT-architectured 1-D ZnO nanocomposites for azo dyes adsorption, photocatalytic degradation, and biological applications

A study has synthesized a composite of carbonaceous nanomaterials, including functionalized multi-walled carbon nanotubes (f-MWCNT) and reduced graphene oxide (rGO), with 1D-architectured zinc oxide nanorods (ZnO NRs), for applications in adsorption and sunlight-assisted photocatalytic degradation. We modified the composite with 1% w/w rGO and f-MWCNT. We studied the adsorption and photodegradation of azo dyes using ZnO and its nanocomposites. The photocatalysts of RZnO and CZnO nanocomposite degraded RhB, MB, CV, MO, and CR dyes with a degradation percentage of 92 to 97%. The nanocomposite demonstrated superior antimicrobial and antioxidant properties compared to ZnO NRs, highlighting their potential in drug delivery.
