Photocatalytic, electrochemical, antibacterial and antioxidant behaviour of carbon-sulphur Co-doped zirconium (IV) oxide nanocomposite
In this work, carbon-sulphur co-doped ZrO2 nanocomposites were synthesised using the aqueous leaves extract of Plumeria acuminate, zirconia salt precursor, polyvinylpyrrolidone and sodium hydrosulphide. The structural, elemental and morphological properties of the synthesized nanomaterials were exam...

| description | In this work, carbon-sulphur co-doped ZrO2 nanocomposites were synthesised using the aqueous leaves extract of Plumeria acuminate, zirconia salt precursor, polyvinylpyrrolidone and sodium hydrosulphide. The structural, elemental and morphological properties of the synthesized nanomaterials were examined by different analytical techniques UV-visible spectrophotometer, HRSEM-EDS, HRTEM-SAED, XRD and BET. HRSEM analysis of C-S-ZrO2 revealed the presence of spherical and irregular hexagonal shapes. The XRD pattern demonstrated formation of crystalline tetragonal and a mixture of tetragonal and orthorhombic phases for ZrO2 and C-S-ZrO2 composite with an average size of 20.03 nm and 12.40 nm respectively. The band gap values of 5.2 eV and 3.4 eV were obtained for ZrO2 and C-S-ZrO2 respectively. The adsorptive and photocatalytic properties of ZrO2 based nanomaterials for the removal of azo dye in local dyeing wastewater were investigated. The electrochemical activities of the nanomaterials were assessed using cyclic voltammetry, while Agar well diffusion, DPPH and ABTS methods were followed for the determination of antibacterial and antioxidant activities of ZrO2 and C-S-ZrO2. The maximum COD, BOD, TOC, SO42-, CO32, Cl− and NO3−removal efficiencies of 77.3%, 87.6%, 97.7% 63.9%, 84.4%, 70.3% and 83.3 % at 120 min were obtained using C-S-ZrO2 composite due to its higher surface area (80.165 m2/g) and lower band gap (3.4 eV) compared with ZrO2 (10.682 m2/g). Carbon-sulphur co-doped ZrO2 composite exhibited moderate antioxidant activity and increased peak current than other ZrO2 based nanomaterials due to its highest surface area than ZrO2 alone. The order of antibacterial activity of the nanomaterials against the Salmonella typhi, Pseudomonas aeruginosa, Escherichia coli is ZrO2-C-S (15.40±1.11 mm, 25.10±1.80 mm, 20.03±2.50 mm) > C-ZrO2 (9.45±2.65 mm, 11.18±0.33 mm, 15.45±3.25 mm) > S-ZrO2 (7.52±1.55 mm, 12.45±0.11 mm, nil) >ZrO2 (6.33±0.90 mm, 4.25±0.52 mm, nil). The experimental data best described by pseudo-first-order, followed by parabolic-diffusion and modified Freundlich models. The results showed that the synthesized C-S-ZrO2 nanocomposite is highly efficient with excellent regenerative potential even after five cycles. |
