“…Figure 2 (curves c and d) show that the diffraction peaks of the CS- The peak intensity of SnO 2 decreases due to the loading minimum molar concentration of ZnO to distort the rutile structure due to the substitution of impurities (Zn 2+ ) or substituted into the interstitial position of SnO 2 . Generally the SnO 2 particles are of semicrystalline nature and have low intensity, as reported in some previous work [39]. The SnO 2 particles incorporated on chitosan, thus the biopolymer is suppressed by the SnO 2 crystalline peaks.…”

A new chitosan (as biotemplate)-zinc-tin oxide hybrid structure was successfully synthesized by a chemical precipitation method and annealed at 500 °C. We studied the structural changes, optical, thermal and photo catalytic properties. The chemical bonding of the Zn-O and Sn-O-Sn functional groups were confirmed by FT-IR absorption peaks appearing at 538 and 635 cm −1 . The different ratio of ZnO to SnO 2 particles on the biotemplate matrix altered the morphology of the hybrids from an agglomerated state to a microcrystalline form confirmed by HR-SEM and TEM analysis. The formation of a Zn 0.15 Sn 0.85 O hybrid structure was observed in the visible light region, with an energy band gap of ∼3.19 eV and higher surface area of 98 m 2 g −1 . The thermal property shows that CS-Zn 0.15 Sn 0.85 O has a higher thermal stability than a CS-Zn 0.25 Sn 0.75 O hybrid structure. The results demonstrate that the biotemplate-zinc-tin oxide hybrid structure has a reinforced effect compared to the other components. Therefore, a biotemplate-based zinc-tin oxide hybrid structure could be a promising material for better dye removal efficiency, which was obtained for ∼100 and 96% with MB and RY-15 dyes.

“…Thus, many antimicrobial single oxide NPs are demonstrated; however, current situation demands newer materials for better efficacy than the reported results . Presently, researchers have also focused toward the combination of two or more metals/metal oxide NPs for many purposes such as photocatalytic activity, antibacterial purposes, − making optical devices, and energy harvesting, to solve the environment issues and so forth. These NPs can be synthesized through various methods, for example, solvothermal, sol–gel, microwave assisted, and so forth.…”

In this work, mesoporous (pore size below 4 nm) composite nanoparticles of ZnO–Ag2O/Ag, ZnO–CuO, and ZnO–SnO2 of size d ≤ 10 nm (dia.) have been synthesized through the in situ solvochemical reduction method using NaBH4. These composite nanoparticles exhibited excellent killing efficacy against Gram-positive/negative bacterial and fungal strains even at a very low dose of 0.010 μg/mL. Additionally, by applying the in silico docking approach, the nanoparticles and microorganism-specific targeted proteins and their interactions have been identified to explain the best anti-bacterial/anti-fungal activities of these composites. For this purpose, the virulence and resistance causing target proteins such as PqsR, RstA, FosA, and Hsp90 of Pseudomonas aeruginosa, Acinetobacter baumannii, Klebsiella pneumoniae, and Candida albicans have been identified to find out the best inhibitory action mechanisms involved. From the in vitro study, it is revealed that all the composite nanoparticle types used here can act as potent antimicrobial components. All the composite nanoparticles have exhibited excellent inhibition against the microorganisms compared to their constituent single metal or metal oxide nanoparticles. Among the nanoparticle types, the ZnO–Ag2O/Ag composite nanoparticles exhibited the best inhibition activity compared to the other reported nanoparticles. The microorganisms which are associated with severe infections lead to the multidrug resistance and have become a huge concern in the healthcare sector. Conventional organic antibiotics are less stable at a higher temperature. Therefore, based on the current demands, this work has been focused on designing inorganic antibiotics which possess stability even under harsh conditions. In this direction, our developed composite nanoparticles were explored for potential uses in the healthcare technology, and they may solve many problems in global emergency and epidemics caused by the microorganisms.

“…A well-crystallized material of ZnWO 4 -(ZnO) composite was prepared by sol-gel synthesis method from aqueous solutions of Zn 2+ and WO 4 2at pH = 7 or pH = 10 without the addition of any surfactant [50]. Different structures and morphologies of ZnO/SnO 2 nanocomposites have been prepared by sol-gel route followed by annealing the precipitate at 600 and 750 °C [51]. The prepared composites are potentially used in solar cells, gas sensors, photocatalysts, and optoelectronics.…”

Zinc oxide (ZnO) is used for various purposes because of its special physico-chemical properties, including large band gap, high binding energy of exciton, nontoxicity, high chemical and thermal stability, large piezoelectric constants, and wurtzite crystal structure with various and widespread applications in electronics, optoelectronics, biochemical sensing, biomedical, and energy-saving systems. This review mainly aimed to present the recent improvement in ZnO-based composite materials with utilization in energy storage systems with a specific focus on lithium-ion batteries, dye-sensitized solar cells, and supercapacitors. The first part of this paper looks at the structure and properties of ZnO and then describes some of the most common synthesizing methods of ZnO composites, including electrochemical, chemical, solvo/hydrothermal, and physical deposition methods. Finally, the recent advancement of ZnO-based composite materials applied in energy storage systems was discussed.
