“…A substantiated comparison of the inhibition zone diameter with respect to S. aureus and E. coli bacteria monitored in various doped (single or double) ZnO materials is shown in Table 3. From the table, it can be seen that Cd, Ba co‐doped ZnO nanorods prepared show enhanced antibacterial activity as observed in the current study when compared to Cd, Ba co‐doped CuO, 28 Fe, Co co‐doped ZnO, 26 Mn doped ZnO, 58 Ag doped ZnO, 58 Cu doped ZnO, 17 Sn doped ZnO, 17 Ti doped ZnO, 24 Cd doped CuO, 28 Ti doped MgO, 60 and Ba doped CeO 2 51 nanoparticles. The impressive antibacterial activity of Cd, Ba co‐doped ZnO nanoparticles is because of the low crystallite size (42.35 nm), decrease in lattice strain, and increase in dislocation density, as evidenced from the XRD data.…”

“…The second‐order mode identified at ∼ 314 cm −1 is ascribed to the difference of E 2H − E 2L 46 . The Raman band observed at ∼ 367 cm −1 is assigned to the A 1 (TO) mode, which is considered to be the first‐order optical mode of hexagonal wurtzite ZnO 24 . The Raman peak noted at ∼ 401 cm −1 is because of the polar phonon mode E 1 (TO), which responds to the defect change caused by the oxygen vacancy and free carriers 47 .…”

“…The lattice constants of the samples were determined employing the equation 30

\frac{1}{d_{italichkl}^{2}} goodbreak= \frac{4}{3} \frac{h^{2} + italichk + k^{2}}{a^{2}} goodbreak+ \frac{1^{2}}{c^{2}}

The mean crystallite size of the prepared nanoparticles was computed by Debye–Scherrer's equation 24

D goodbreak= \frac{Kλ}{β \cos θ}

where K is known to be the shape factor (0.94) whereas β is termed as the full width at half maximum (FWHM) intensity of the specific diffracting peak, and λ is the wavelength of X‐ray (0.1541 nm) whereas θ is the Bragg's diffraction angle.…”

“…Analyzing the table, it is identified that the dislocation density of Cd, Ba co‐doped ZnO (5.57 × 10 −4 nm −2 ) is greater than that of Cd doped ZnO (2.68 × 10 −4 nm −2 ). It is obvious that the decrease in crystallite size (W–H method) brings out an increase in the dislocation density, which conveys that the stacking fault might decrease as a function of dislocation density 24 . The strain increases in the Cd doped ZnO compared to the Cd, Ba co‐doped ZnO nanoparticles.…”

“…Besides the UV‐shielding performance, doped ZnO has also been widely investigated for its outstanding antibacterial activity toward Staphylococcus aureus ( S. aureus ) and Escherichia coli ( E. coli ) 17 . The process of doping with different elements (La, Sr, Ta, Cu, Ni, Sn, Ti, Mg, and Ba) in ZnO is the simplest way to vary the antibacterial properties considerably such that ZnO consistently inculcates more research interest till date 18–24 . The co‐doped ZnO such as Al‐Cr, 25 Sn‐Cu, 17 Fe‐Co, 26 and La‐Cu 27 attracts much more attention for the investigation of antibacterial activity.…”

The utilization of highly efficient ultraviolet (UV)-attenuating materials has inevitably signaled an ever-increasing demand to mitigate the impending pessimistic impact of UV rays that consistently depletes the ozone atmosphere. In this context, a highly efficient Cd, Ba co-doped ZnO nanomaterial has been prepared using a facile wet chemical approach. X-ray diffractometer analysis indicates the evolution of wurtzite structure of ZnO with a slight peak shift towards the higher angle upon co-doping which ascertains the impacted lattice contraction. N 2 adsorption/desorption isotherms of the material supplement magnificently a typical type-IV behavior displaying an H1 type hysteresis loop at high pressures whereby authorizing the open meso-porous characteristics. The resulting Cd, Ba co-doped ZnO nanorods disclose integrated performances of widespread polychromatic UV-visible luminescent emission, wide band gap, and enhanced UV absorbance. In particular, Cd, Ba co-doped ZnO nanorods impart a positive UV-blocking execution of 97% for UVA at 360 nm and 88% for UVB at 320 nm, which is found to be higher than most of the reported ZnO-related materials. Besides these intriguing aforementioned properties, co-doping is also appropriate for imparting better bacterial inhibition against the two tested strains (Escherichia coli and Staphylococcus aureus). Altogether, these results indicate that the co-doped ZnO nanorods developed in the current investigation could potentially serve as a propitious alternative UV-blocking material, especially for biomedical applications.

Crystal violet (CV), a cationic dye, has been demonstrated to be a powerful carcinogen, a mitotic toxin and poisonous to mammalian cells such that the predominant presence of the dye invariably causes several effects of destruction to mankind and it necessitates a clarion call to do away with this nuisance before it can produce a snowball effect. The recent widespread reporting of the photocatalysis‐mediated degradation of CV as an emerging technique for removing this dangerous dye from aqueous mediums highlights its effectiveness. Numerous researchers have contributed substantially to describing how photocatalysis‐based nanomaterials could be used to degrade CV. The fundamentals and the factors that predominantly influence CV degradation are highlighted in this work. These factors include the nature of nanomaterials, catalyst concentration, dye dosage, pH of the solution in use, temperature and light intensity. Additionally, thorough kinetics and mechanistic descriptions are also included to give crucial insights into the light‐mediated reaction of CV. The present study's findings have the potential to alleviate practitioners and researchers of the burden of having to navigate through numerous studies under each category of parameters to get an exhaustive overview of all of the different variables that may affect the photocatalytic degradation of CV dye. In order to further enhance the photocatalytic degradation efficiency of CV, researchers can expand on this study by investigating novel strategies to lessen the impact of certain elements that adversely affect the photocatalytic reaction process. The potential prospects for extending the advancement of scientific study in this area are also explored. © 2024 Society of Chemical Industry (SCI).
