“…Therefore, when building materials from nanoscale units, these uncertainties are included to harmonize the various effects [55,56]. Recent publications advocating nanoarchitectonics show that it is widely applied in academic fields such as materials synthesis [57][58][59], structural control [60][61][62][63], physical phenomena [64][65][66], and basic biochemistry [67][68][69], as well as in applied fields such as catalysis [70][71][72], sensors [73][74][75], devices [76][77][78], energy [79][80][81], environment [82][83][84][85], and medicine [86][87][88][89]. Since all the materials are composed of atoms and molecules, nanoarchitectonics is considered a universal unified concept that can be applied to all targets.…”

The development of nanotechnology has provided an opportunity to integrate a wide range of phenomena and disciplines from the atomic scale, the molecular scale, and the nanoscale into materials. Nanoarchitectonics as a post-nanotechnology concept is a methodology for developing functional material systems using units such as atoms, molecules, and nanomaterials. Especially, molecular nanoarchitectonics has been strongly promoted recently by incorporating nanotechnological methods into organic synthesis. Examples of research that have attracted attention include the direct observation of organic synthesis processes at the molecular level with high resolution, and the control of organic syntheses with probe microscope tips. These can also be considered as starting points for nanoarchitectonics. In this review, these examples of molecular nanoarchitectonics are introduced, and future prospects of nanoarchitectonics are discussed. The fusion of basic science and the application of practical functional materials will complete materials chemistry for everything.

“…Many materials that are capable of removing dyes have been described in the literature. Silica hydrogels, [16] bentonite/ alginate composites, [17] cellulose-based composites, [18] and chitosan [19,20] have been successfully used in water decoloura-tion processes. Additionally, many materials derived from biomass waste [21][22][23] have been used to remove dyes.…”

Novel Synthesis Strategy for the Use of Silica‐Based Composites Modified With Styrene‐Acrylic Copolymer as High‐Performance Adsorbents for Cationic Dyes Removal From Aqueous Environment

Adsorption is a reliable method for removing organic pollutants from water. This article provides data on the use of hybrid composites as adsorbents for Methylene Blue (MB) and Rhodamine 6G (R6G) uptake from aqueous solutions. The organo‐inorganic spherical particles were prepared using tetraethyl orthosilicate and a styrene‐acrylic copolymer through a one‐pot sol‐gel technique. The powder structures were characterised using various methods, including elemental analysis, acid‐base titration, zeta potential measurement, IR spectroscopy, thermogravimetric analysis, low‐temperature nitrogen adsorption, and scanning electron microscopy. The results revealed that the adsorption process demonstrated a preference for a pH of 6 in the case of MB, whereas for R6G, the optimal pH for adsorption was observed to be 7. The findings indicated that the pseudo‐second‐order model accurately described the kinetic data, while the equilibrium data aligned with the Freundlich model. The maximum adsorption capacities were determined to be 212.5 mg/g for MB and 323.1 mg/g for R6G, suggesting that both chemisorption and physical adsorption occurred on the surface of the adsorbent material. The composites were found to be regenerable with an HCl:EtOH mixture up to 3 cycles. These findings suggest that silica/styrene‐acrylic copolymer composites are promising sorbents for removing MB and R6G dyes from aqueous solutions.

“…The presence of dyes in the environment has serious negative consequences for nature and human health, as dyes can be toxic to aquatic organisms that are part of the food chain [5,6] . To avoid the negative impact on the environment and human health, the treatment of dyes wastewater should be carried out using environmentally friendly technologies, such as adsorption, membrane filtration etc [7–12] . The most promising technologies for cleaning dyes contaminated wastewater are advanced oxidation processes (AOPs), which can effectively remove organic compounds [13–17] .…”

[13][14][15][16][17] The advantage of AOPs over other treatment methods is that they are "environmentally friendly" because they do not transfer pollutants from one phase to another (e. g., coagulation and adsorption) and do not generate large amounts of hazardous sludge as in the case of biological treatment.…”

Magnetite (Fe3O4) is one of the widely used materials as a catalyst in the photo‐Fenton process for the oxidation of dyes. We report about the electrochemical synthesis of the superparamagnetic Fe3O4 nanoparticles. The structure, morphology, chemical composition, and chemical state of the catalyst were characterized. The synthesized samples of superparamagnetic Fe3O4 nanoparticles were characterized using scanning electron microscopy, X‐ray diffraction spectroscopy (XRD), Raman shift spectroscopy, and vibrating magnetometer (VSM). The diffraction peaks and Raman shift spectra confirm the formation of Fe3O4. Superparamagnetic Fe3O4 nanoparticles were used as a catalyst for the oxidation of Rhodamine B (RhB) in a photo‐Fenton‐like process. The effect of operating parameters, including H2O2 concentration, catalyst concentration, and RhB concentration, on the RhB decomposition efficiency was investigated. The rate of color removal was 85 % after 12 minutes at RhB concentration of 2 mg/L, H2O2 concentration of 0.18 mM, and Fe3O4 concentration of 0.2 g/L. In addition, electrochemically synthesized superparamagnetic Fe3O4 nanoparticles showed that the catalyst activity decreased by only 7 % during recycling experiments, indicating long‐term stability of the sample.
