“…MONPs have numerous characteristics, such as specific adsorption properties [ 20 ], magnetic features, and redox capabilities. Therefore, in addition to their ability to improve hydrogels’ electrical, mechanical, and thermal properties, MONPs have been used to enhance adsorption selectivity and catalytic activity in pollutant species degradation [ 21 , 22 ]. By adjusting the external magnetic field, they can also allow for remote control of swelling and analyte adsorption/desorption.…”

Water pollution is caused by multiple factors, such as industrial dye wastewater. Dye-contaminated water can be treated using hydrogels as adsorbent materials. Recently, composite hydrogels containing metal oxide nanoparticles (MONPs) have been used extensively in wastewater remediation. In this study, we use a statistical and artificial intelligence method, based on principal component analysis (PCA) with different applied parameters, to evaluate the adsorption efficiency of 27 different MONP composite hydrogels for wastewater dye treatment. PCA showed that the hydrogel composites CTS@Fe3O4, PAAm/TiO2, and PEGDMA-rGO/Fe3O4@cellulose should be used in situations involving high pH, time to reach equilibrium, and adsorption capacity. However, as the composites PAAm-co-AAc/TiO2, PVPA/Fe3O4@SiO2, PMOA/ATP/Fe3O4, and PVPA/Fe3O4@SiO2, are preferred when all physical and chemical properties investigated have low magnitudes. To conclude, PCA is a strong method for highlighting the essential factors affecting hydrogel composite selection for dye-contaminated water treatment.

Soil and water pollution is of significant concern worldwide because of the consequences of environmental degradation and harmful effects on human health. Water bodies are very much polluted from various organic and inorganic pollutants by different human activities, including industrial wastes. Environmental pollution remains high because of urbanization‐induced industrial developments and human lifestyle. It accumulates pollutants in the environment including plants and living organisms. Even mothers’ milk is poisoned because of the uncontrolled, widespread increase in pollution. The discharge levels of organic hydrophobic contaminants in the water and soil are increasing rapidly. This severe pollution must be remediated to upgrade the environment and ensure the safety of human beings. It is vital to eradicate soil and water pollution to guarantee sufficient food and water. Different techniques available to remove the pollutants vary according to the type of pollutants. Hydrophobic contaminants are more dangerous than heavy metals and other pollutants; they cannot be easily removed, requiring special care. Hydrophobic organoxenobiotics released in the environment pose severe contamination in soil and water. Therefore, developing efficient and cost‐effective processes is necessary to remove hydrophobic contaminants from soil and water. With nanoparticle‐mediated remediation techniques, the green‐synthesized nanoparticles exhibit improved performance. This review consolidates reports on the remediation techniques of hydrophobic contaminants, focusing on green‐synthesized remediation agents. The very limited works on green synthesis of polymeric nanoparticles, particularly polyurethane‐based materials for organic contaminants removal demands more attention on this area.

“…Photocatalyst nanoparticles are used in building materials, particularly cement, concrete, mortar, paints, and pavement, to increase self-cleaning qualities and cement performance. Nanoparticles were chosen because of their features on cementitious materials, which include great reactivity, ultrafine particle size, and unique physical and chemical properties [74]. The addition of nanosized materials to traditional structural materials is feasible not only for improving the fundamental qualities of cementitious materials but also for adding functionality such as self-cleaning, antibacterial, and pollution-reducing capabilities [75].…”

Today, the building and construction sector demands environmentally friendly and sustainable protective coatings using inorganic coating materials for safe, non-hazardous, and great performance. Many researchers have been working on sustainable solutions to protect concrete and metal infrastructures against corrosion and surface deterioration with the intention of introducing green alternatives to conventional coatings. This article presents a review of developments of geopolymer pastes doped with different types of photocatalyst precursors including factors affecting geopolymer properties for enhancing coating with photocatalytic performance. Photodegradation using geopolymer photocatalyst has great potential for resolving harmless substances and removing pollutants when energized with ultraviolet (UV) light. Although geopolymer is a potentially new material with great properties, there has been less research focusing on the development of this coating. This study demonstrated that geopolymer binders are ideal precursor support materials for the synthesis of photocatalytic materials, with a significant potential for optimizing their distinctive properties.
