“…As shown by Figures 3 and 4, increasing the Procion red concentration from 50 ppm to 250 ppm caused the degradation percentage to decrease from 96.23% to 67.72% or 28.51% when photocatalyst ZnO-natural zeolite was applied after 120 minutes of irradiation. These results were in accordance with the results of a study conducted by Winatapura et al, in which photodegradation efficiency decreased from 100% to 52% when the Methylene blue dye concentration increased from 10 to 40 ppm (Winatapura et al, 2016). In the present study, increasing the Procion red concentration from 50 to 250 ppm decreased the average degradation percentages by 20.23%, 39.54, and 32.88% for the application of zeolites alone, ZnO alone, and natural ZnO-zeolite photocatalysts, respectively.…”

“…Many efforts have been made to enhance the photocatalytic performance, especially in dye degradation. Such efforts have involved making ZnO-zeolite composites by impregnation methods (Salam et al, 2018), doping ZnO nanoparticles with natural zeolite (Rahman et al, 2018), and adding noble metals, such as Ag nanoparticles (Kusdianto et al, 2019) and Fe3O4 (Winatapura et al, 2016). ZnO has a low capacity for adsorption as a photocatalyst, but ZnO photocatalysts can be combined with adsorbents, such as zeolite, to face this problem (Wismayanti, 2015).…”

The development of textile factories has had a significant impact on the environment because dye wastewater is difficult to degrade. The handling of textile wastewater usually involves the adsorption method, in which pollutants only transfer to another phase. As an alternative solution, a photodegradation method was developed using photocatalyst material assisted by ultraviolet irradiation. In this photodegradation method, dye substances are broken down into components that are simpler and safer for the environment. The possibility of using sunlight as a radiation source makes this a particularly promising method for countries such as Indonesia. Procion red, one of the most commonly utilized synthetic dyes in the home textile or Batik industry, was used as a model pollutant in this study. The objectives of the present research were to synthesize and characterize a nano-photocatalyst of ZnO-natural zeolite with the capacity to degrade Procion red. This nano-photocatalyst was synthesized using the sol-gel method, by which Zn(CH3COO)2 2H2O was used as a precursor and combined with natural zeolite to increase its photocatalytic ability. The nano-photocatalyst was characterized using X-ray diffraction (XRD), scanning electron microscope/energy dispersive X-ray spectroscopy (SEM/EDX), and Brunauer-Emmett-Teller (BET). The activity of nano-photocatalyst ZnO-natural zeolite was compared to ZnO alone and natural zeolite alone in terms of its ability to degrade Procion red. An average photocatalyst crystallite diameter of 82 nm was achieved, proving that a nano-sized photocatalyst of ZnO-natural zeolite was successfully synthesized. BET characterization showed that nanophotocatalyst ZnO-natural zeolite had a specific surface area of 14.84 m 2 /g, a pore size of 32.71 nm, and a pore volume of 0.12 cm 2 /g. A peak Procion red degradation percentage of 96.23% was obtained using nano-photocatalyst ZnO-natural zeolite after 120 minutes of irradiation under sunlight applied to a Procion red concentration of 50 ppm.

“…Thus, thanks to the unique and compatible properties of their structures, Fe3O4 and ZnO allow the production of a higher performance hybrid or composite nanostructure in future applications. In previous studies, sol-gel [4,5], co-precipitation [6], deposition [7], wet milling [8], microwave assisted [9], and wet chemical [10] methods were used for the synthesis of ZnO/Fe3O4 nanocomposites.…”

In this study, ZnO@Fe3O4 composite nanostructures were synthesized using the hydrothermal method. X-ray diffraction analysis was performed for the structural characterization of nanostructures obtained with the addition of Fe3O4 at different ratios, and no impurity peaks were found. Scanning electron microscope (SEM) and transmission electron microscope (TEM) were used for morphological imaging. It was understood that ZnO nanoparticles were decorated around Fe3O4 in the morphology of nanostructures. Fe, Zn, and O peaks were detected in elemental analysis. Energy band gaps of ZnO@Fe3O4 nanocomposite structures were obtained from absorbance data collected by use of UV-VIS spectrometer. The band gap values of nanostructures were calculated to be in the range of 2-2.1 eV. Magnetic properties were determined using a vibrating sample magnetometer (VSM), and the values of 3.76 emu/g and 7.96 emu/g were found depending on the Fe3O4 content. Although these values show a limited ferromagnetic property, they are important in optoelectronic and medical imaging applications due to the advanced optical and electronic properties of ZnO. Hidrotermal yöntem kullanılarakZnO@Fe3O4 kompozit nanoyapıların sentezi ve karakterizasyonu Anahtar Kelimeler Nanokompozit ZnO@Fe3O4, Morfo-yapısal karakterizasyon, Medikal görüntüleme, Manyetik ve optik özellikler Öz: Bu çalışmada, ZnO@Fe3O4 kompozit nanoyapılar hidrotermal yöntem kullanılarak sentezlenmiştir. Farklı oranlarda Fe3O4 katkısıyla elde edilen nanoyapıların yapısal karakterizasyonu için X-ışını kırınım analizi gerçekleştirildi ve herhangi bir safsızlık pikine rastlanmadı. Morfolojik görüntülemede taramalı elektron mikroskobu (SEM) ve geçirimli elektron mikroskobu (TEM) kullanıldı. Nanoyapıların morfolojisinde Fe3O4 etrafında ZnO nano taneciklerinin dekore edildiği anlaşılmıştır. Elemental analizde ise Fe, Zn ve O pikleri kaydedilmiştir. ZnO@Fe3O4 nanokompozit yapıların bant aralığı enerjileri Uv-Vis spektromotresi aracığılıyla elde edilen absorbans datalarından elde edilmiştir. Nanoyapıların bant gap değerleri yaklaşık olarak 2-2.1 eV aralığında hesaplanmıştır. Manyetik özellikler ise Vibrating Sample Magnetometer (VSM) kullanılarak tespit edildi ve Fe3O4 katkı oranına bağlı olarak 3.76 emu/g ile 7.96 emu/g değerleri bulundu. Bu değerler sınırlı bir ferromanyetik özellik göstermesine rağmen ZnO'nun sahip olduğu gelişmiş optik, elektronik özelliklerinden dolayı optoelektronik ve medikal görüntüleme uygulamalarında önem arz etmektedir.

A magnetic Fe3O4/ZnO nanocomposite (NCs) was prepared by a high energy milling (HEM) method. In the present study, the ZnO catalyst was prepared through two ways. The ZnO was synthesized by coprecipitation method (ZnO (S)), and ZnO directly used a commercial product (ZnO (Ald)). The prepared NCs were characterized using X-ray diffraction (XRD), vibrating sample magnetometer (VSM), Fourier transform infrared (FTIR), transmission electron microscope (TEM), and UV-Vis spectrophotometer. The XRD refinement indicates that Fe3O4 nanoparticle (NP) is a single phase and well indexed to cubic spinal structured magnetite. The Fe3O4/ZnO (S) and Fe3O4/ZnO (Ald) NCs are consisted of Fe3O4 and ZnO phases. The VSM result show that Fe3O4 NP, Fe3O4/ZnO (S), and Fe3O4/ZnO (Ald) NCs possess super-paramagnetic properties with saturation magnetization (Ms) is 102 emu.g-1 , 28 emu.g-1 and 26 emu. g-1 , respectively. The TEM observation shows that the average diameter of Fe3O4 is approximately 15 nm, while the thickness both of ZnO shell is ranging 20 nm-50 nm. The average diameter of TiO2 P25 particle as catalyst was observed about 20 nm. The photocatalytic activity of catalysts were evaluated based on the degradation of methyl orange (MO) dye solution. The result shows that at pH = 7, the Fe3O4/ZnO (Ald) NC can degrade the pollutant in MO dye solution to 99 %, where as at pH = 3, the catalyst TiO2 P25 degrade only 96%.
