“…However, the pore size of the composite material remained similar to that of malachite, suggesting that the addition of Fe 3 O 4 did not significantly affect the pore structure of the composite material. Therefore, while the Fe 3 O 4 –malachite NCs may still be effective for various organic pollutants and pesticide adsorption, the reduced specific surface area should be taken into account when designing applications for this material. − …”

“…SiO 2 can improve the stability and reusability of the adsorbent, making it more practical for large-scale applications. 22,40,42,44−48 Studies have shown that the coupling of SiO 2 with Fe 3 O 4 can significantly increase the adsorption capacity for organic contaminants such as phenol, 40 methylene blue, 41 and fluoride. 42 TiO 2 coupling with Fe 3 O 4 can enhance the photocatalytic activity of the material, allowing for the degradation of contaminants like chlorpyrifos under light irradiation.…”

This study assessed the efficacy of adsorption for eliminating the agricultural pesticide cypermethrin (CP) from wastewater using various adsorbents: silica, malachite, and magnetite. Magnetic nanocomposites (NCs) (with varying amounts of Fe 3 O 4 0.1, 0.25, 0.5, 1.0, and 1.5 wt/wt %) were synthesized, including Fe 3 O 4 nanoparticles (NPs), bicomposites, and tricomposites, calcined at 300 and 500 °C, and then tested for CP removal. The study was conducted in two phases, with the objective of initially assessing how effectively each individual NP performed and then evaluating how effectively the NCs performed when used for the adsorption of CP. Notably, the Fe 3 O 4 −malachite combination exhibited superior CP removal, with the 0.25-Fe−M NC achieving the highest adsorption at 635.4 mg/g. This success was attributed to the large surface area, magnetic properties of Fe 3 O 4 , and adsorption capabilities of malachite. The Brunauer−Emmett−Teller (BET) isotherm analysis indicated that the NCs had potential applications in adsorption and separation processes. The scanning electron microscopy and transmission electron microscopy revealed the spherical, irregular shaped morphology of the synthesized NPs and NCs. However, the X-ray diffraction (XRD) pattern of surface functionalized materials such as surface functionalized malachite [Cu 2 CO 3 (OH) 2 ] with Fe 3 O 4 and SiO 2 may be complicated by the specific functionalization method used and the relative amounts and crystallographic orientations of each component. Therefore, careful interpretation and analysis of the XRD pattern, along with other techniques, are necessary for accurate identification and characterization of the functionalized material. The originality of this study lies in its comprehensive investigation of several adsorbents and NCs for CP removal at neutral pH. The innovation stems from the synergistic action of Fe 3 O 4 and malachite, which results in improved CP removal due to their combined surface properties and magnetic characteristics. The application of magnetic NCs in adsorption and separation, as validated by BET isotherm analysis, highlights the potential breakthrough in addressing pesticide contamination.

Water is an essential source of life, thus regulating its purity is critical in daily living. Water has a high acid content (pH) and contains a variety of harmful chemical elements such as iron (Fe), copper (Cu), sulphate (SO4), nitrate (NO3), chloride (Cl), and other dangerous bacteria. The goal of this research is to create wastewater management such that it can be used by the community. The process involves creating Fe3O4 catalysts that have been modified using SiO2 and TiO2. The application of dirty water employs Fe3O4/SiO2/TiO2 to bind contaminants in polluted water. The results of the photocatalyst process carried out by Fe3O4/SiO2/TiO2 reach 90% in 180 minutes of UV light irritation so that it can degrade water pollutants such as methylene orange.

“…Discharge of wastewater containing organic pollutants into water resources makes water treatments more important (Lee and Park, 2013). Although there are various water treatment methods such as adsorption, biodegradation, photocatalysis and ozonolysis, photocatalysis has been widely used because it is environmentally friendly, economical and efficient (Shilpa et al, 2023b;Ye et al, 2020).…”

Purpose Three-dimensional (3D) printing is popular for many applications including the production of photocatalysts. This paper aims to focus on developing of 3D-printed photocatalyst-nano composite lattice structure. Digital light processing (DLP) 3D printing of photocatalyst composites was performed using photosensitive resin mixed with 0.5% Wt. of TiO2 powder and varying amounts (0.025% Wt. to 0.2% Wt.) of graphene nanoplatelet powder. The photocatalytic efficiency of DLP 3D-printed photocatalyst TiO2 composite was investigated, and the effects of nano graphite powder incorporation on the photocatalytic activity, thermal and mechanical properties were investigated. Design/methodology/approach Methods involve 3D computer-aided design modeling, printing parameters and comprehensive characterization techniques such as structural equation modeling, X-ray diffraction, thermogravimetric analysis, Fourier-transform infrared (FTIR) and mechanical testing. Findings Results highlight successful dispersion and characteristics of TiO2 and graphene nanoplatelet (GNP) powders, intricate designs of 3D-printed lattice structures, and the influence of GNPs on thermal behavior and mechanical properties. Originality/value The study suggests applicability in wastewater treatment and environmental remediation, showcasing the adaptability of 3 D printing in designing effective photocatalysts. Future research should focus on practical applications and the long-term durability of these 3D-printed composites. Graphical abstract
