“…5) of the SrZnO2 nanoparticles shows that the shapes of nanocomposites are close to rod shaped. The flower like shapes of hexagonal rods of ZnO is also confirmed form the previous work of the author [8]. It is expected that the initially form flower like structures can split into its hexagonal rods during sonochemical synthesis.…”

“…When 2 ml of ethylene-di-amine as the capping agent was added to a well stirred mixture of strontium chloride hexahydrate solution (SrCl 2 .6H 2 O) and zinc acetate [Zn(CH 3 OO) 2 .2H 2 O]. The solution is then sonicated with dropwise addition of KOH as reducing agents, then zinc (Zn(OH) 2 ) and strontium hydroxide (Sr(OH) 2 ) are formed [8,9]. When the sonochemical process continued, the Zn(OH) 2 and Sr(OH) 2 is separated into Zn 2+ and Sr 2+ ions and OH − radical forming ZnO and SrO nuclei according to the last reaction as given in the Fig.…”

Single phase SrZnO2 nanorods with average size of around 100 nm are synthesized by probe sonicator using ultrasonic waves at 60 W, 6 kHz for 3 h to observe the changes in optoelectronic properties of ZnO. The as grown SrZnO2 has a single phase rod shaped structure. These nanorods were broadly characterized by different instrumental techniques like TEM, FESEM, EDAX, XRD, UV–Visible and FTIR for analysis of size, crystal structure, morphology and composition which acknowledge the formation of single phase crystalline ZnO and slightly amorphous SrZnO2 nanorods. All these results suggest that single phase SrZnO2 nano-composites can easily be synthesized by one step sono-chemical method. Graphic abstract

“…In addition, there were some different characteristic peaks at the wide angle XRD spectra of loaded samples at 2 θ angles of 31.8°, 34.4°, 36.2°, 47.5°, and 56.6° which are associated to (100), (002), (101), (102), and (110). These results indicated that the synthesised ZnONPs on the cotton fibres surface has a hexagonal wurtzite crystal structure [29]. The intensity of the diffraction peaks at 2 θ equal to 34.4 (002) was higher than others and appeared at very low intensity for Zn 0.009 Na.…”

In this study, an in-situ approach was used to synthesise zinc oxide nanoparticles on the surface of cotton fabric. The effect of alkaline pre- and after-treatment and Zn(2+) concentration was studied on the morphological, structural, thermal, photocatalytic, and antibacterial properties of loaded cotton fabrics. Scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffractometer, thermogravimetric analysis, and attenuated total reflection Fourier transform infrared spectrometer were used to characterise the properties of loaded cotton fabrics. Alkaline after-treatment of cotton fabric presented more dispersed zinc oxide nanoparticles, and an increase in Zn(2+) concentration led to form agglomerated nanoparticles on the surface of cotton fibres. The loaded cotton fabrics with zinc oxide nanoparticles presented an inhibition zone against Staphylococcus aureus and Escherichia coli. In addition, the stain of methylene blue on the surface of loaded samples was degraded after irradiated under visible light.

“…5. Due to the position of these new peaks, it can be concluded that the synthesized ZnO particles have a hexagonal wurtzite crystal structure 27 . The characteristic peaks of cellulose structure were appeared in all untreated and loaded samples with nanoparticles near to the 2θ angles of 14.8°, 16.8°, 22.2°, and 34.1°, which are associated to (101), (101), (002), and (040).…”

The paper describes the study of photocatalytic oxidation and antibacterial properties of cotton fabric treated with zinc oxide/silver (ZnO/Ag) nanocomposites. The ZnO nanoparticles were synthesized by an in situ approach on the surface of activated cotton fibers with seeded Ag nanoparticles. The effect of Ag nanoparticles seeding and synthesis temperature on the morphological, thermal, photocatalytic and antibacterial properties of ZnO/Ag nanocomposites treated cotton fibers were characterized using scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffractometer, thermo gravimetric analysis, Attenuated Total Reflection-Fourier Transform Infrared spectrometer. Synthesizing ZnO nanoparticles on the surface of un-activated cotton fibers lead to the formation of agglomerated nanoparticles while the Ag nanoparticles seeded cotton fibers prevented forming the same. The results indicated the presence of ZnO/Ag nanocomposites on the coated cotton fabrics, and all loaded samples presented an inhibition zone against S. aureus and E. coli bacteria.
