Coprecipitation synthesis of zinc ferrit (FE₂O₃/ZNO) nanoparticles prepared by CTAB surfactant

Abstract

ABSTRACT

Preparation, Properties, and Microbial Impact of Tungsten (VI) Oxide and Zinc (II) Oxide Nanoparticles Enriched Polyethylene Sebacate Nanocomposites

“…The solution was shifted to a proper autoclaving system and aged for 2 days at 180 °C to get the final product. Further, zinc oxide was prepared through the coprecipitation process in presence of CTAB [ 51 ]. CTAB based zinc chloride hexahydrate was dissolved in distilled water (mole ratio of 0.8), 2 M aqueous NaOH medium was gradually added until pH raised to 11.…”

“…As an initial step, unbundling and dispersion of solid PES was operated by addition of about 10 g of resin to 50 mL of distilled water with sturdy stirring for 3 h at ambient temperature ( Figure 1 a). Thereafter, 0.05 g of nano-sized WO 3 and ZnO as a solid powder was added quietly under vigorously stirring for 3 h (Wt.% 0.05 MO x /PES) [ 51 ]. Ultimately, the suspension was strongly stirred for 3h and aged for 48 h at 100 °C in a proper autoclaving system.…”

Novel g-C3N4/Fe-ZnO/RGO nanocomposites with boosting visible light photocatalytic activity for MB, Cr (VI), and outstanding catalytic activity toward para-nitrophenol reduction

“…However, there are some shortcomings which have hindered the industrial application of pristine ZnO to a greater extent [3,9,10]. ZnO can only absorb UV light due to its wide band gap (3.2 eV), which is approximately 3%-5% of the whole solar energy [11,12]. Therefore, much effort has been made for perfecting the intrinsic physicochemical properties of ZnO as well as an enhancement for photocatalytic performance [13,14].…”

Study of α-Fe2O3@ ZnO nanoleaves: Morphological and optical study

“…However, many of these methods suffer from several drawbacks such as long reaction time, requirement of high reaction temperature. Coprecipitation synthesis is regarded as a versatile tool for the synthesis of MOS NPs and is a simple and economic route to synthesize the Fe 2 O 3 @ZnO NPs [70] . Present study refers to the synthesis of Fe 2 O 3 @ZnO via a direct coprecipitation method and study the morphological and optical properties.…”

“…The crystallite size of the NPs are determined around 42 nm. The morphology of the samples show that the samples change from rod-shape to fern-like Fe 2 O 3 @ZnO nanoleaves after heat treatment [70] . In fact, the PVP and EG stabilizers are removed by annealing process and the atomic and molecular interactions change between particles that lead the fern-like nanoleaves formation [72][73][74][75][76][77] .…”
