“…Traditionally, remediation practitioners focused on either physical cleanup methods, such as soil excavation and disposal at landfill (Qi et al, 2020), or chemical treatment methods, such as in situ chemical oxidation (O'Connor et al, 2018a). In recent years, nature-based solutions, such as phytoremediation and green stabilization, have gained attention among the scientific research community (Wang et al, 2019b;Wang et al, 2020b;Zhang et al, 2020a). For example, microbial strains from unique natural environments are being harvested, cultured, and exploited to render economic and environmentally friendly solutions for soil decontamination (Atashgahi et al, 2018;Bunge et al, 2003).…”

“…Clay minerals, in particular montmorillonite, are also important for soil remediation, as pollutants can be adsorbed on their surface and/or intercalated in the interlayer [8][9][10][11]. The remediation process involves the fundamental role of water as a solvent and is usually controlled by the cation exchange capacity (CEC) of montmorillonite, which can be affected by the surface charge of the 2:1 layers [12][13][14].…”

Montmorillonite is one of the principal mineralogical phases in clay minerals, where its interaction with water and other molecules represents one of the most important aspects and properties for basic science and specific applications. In fact, montmorillonite has many uses in various scientific and technological fields, ranging from environmental remediation to ceramics, food science, and construction/building materials. Several efforts have characterized its structure and physico-chemical properties, especially at the Tetrahedral-Octahedral-Tetrahedral TOT surface. For this purpose, in this work, the authors investigated the structural and electrostatic potential features of the (00l) surface of montmorillonite and the water adsorption process by first principle methods (density functional theory, DFT), considering both static and molecular dynamics approaches. The provided data further extend the knowledge of the modulation of the water molecule adsorption with this important clay mineral.

“…Heavy metal pollution and organic pollution are regarded as the main types of soil pollution because of the large amount among the pollutants [248]. The surface of the contaminated soil with a high concentration of pollutants can easily enter the atmosphere or water under the action of wind and water, respectively, leading to other secondary environmental problems such as air pollution, surface water and groundwater pollution [249][250][251]. Therefore, soil remediation is imminent.…”

A high-efficiency method to deal with pollutants must be found because environmental problems are becoming more serious. Photocatalytic oxidation technology as the environmentally-friendly treatment method can completely oxidate organic pollutants into pollution-free small-molecule inorganic substances without causing secondary pollution. As a widely used photocatalyst, titanium dioxide (TiO2) can greatly improve the degradation efficiency of pollutants, but several problems are noted in its practical application. TiO2 modified by different materials has received extensive attention in the field of photocatalysis because of its excellent physical and chemical properties compared with pure TiO2. In this review, we discuss the use of different materials for TiO2 modification, highlighting recent developments in the synthesis and application of TiO2 composites using different materials. Materials discussed in the article can be divided into nonmetallic and metallic. Mechanisms of how to improve catalytic performance of TiO2 after modification are discussed, and the future development of modified TiO2 is prospected.
