“…Recently, clay minerals are extensively used in modern industry as a necessary industrial raw material [ 13 , 14 ], and the hydration, adsorption, and swelling along with the thermodynamic properties of clay minerals have become research hotspots in the fields of environment and chemical engineering. Illite/iron nanoparticles were synthesized using a liquid-phase reduction method to remove Pb(II) from an aqueous solution [ 15 ]. Pore fluid pressurization caused by the confinement of water in nanometric micropores is one of the main causes of soil instability [ 16 ].…”

Clay minerals inevitably interact with colloidal oxides (mainly iron and aluminum oxides) in the evolution of natural geomaterials. However, the interaction between the clay minerals and the colloidal oxides affecting the stability and the strength of geotechnical materials remains poorly understood. In the present work, the interaction between the clay minerals and the colloidal oxides was investigated by reaction molecular dynamics simulations to explore the mechanical properties of illite-based materials. It was found that the metal atoms of the intercalated amorphous iron and aluminum oxides interact with oxygen atoms of the silica tetrahedron at the interface generating chemical bonds to enhance the strength of the illite-based materials considerably. The deformation and failure processes of the hybrid illite-based structures illustrated that the Al–O bonds were more favorable to the mechanical properties’ improvement of the hybrid system compared with Fe–O bonds. Moreover, the anisotropy of illite was greatly improved with metal oxide intercalation. This study provides new insight into the mechanical properties’ improvement of clay-based materials through metal oxides intercalation.

“…And materials modified by nano-sized zero-valent iron (nZVI, with a size less than 100 nm) have attracted much attention for use in environmental remediation [8][9][10]. Various synthetic methods have been exploited to prepare iron nanoparticles [11][12][13][14][15][16][17]. Due to its considerable specific surface area, nZVI has a high surface energy and high reactivity [18], and therefore it is suitable for the removal of different environmental pollutants [19][20][21][22][23][24][25][26].…”

The removal of Pb(II) from aqueous solutions was investigated using kaolin with two different particle sizes (2.3 and 45 μm) with and without nanoscale zero-valent iron (nZVI, at a Fe content close to 30%). The experimental results show that 2.3 μm kaolin loaded with nZVI (K-nZVI) had the best Pb(II) removal performance under various test conditions. After 24 h, it removed 99.5% of Pb(II) ions in the solution, followed by 45 μm K-nZVI, 2.3 μm kaolin, and 45 μm kaolin (89.01%, 68.8%, and 65.8%, respectively). The removal rates by all four kaolin samples increased with increasing pH in the range of 2-6, and with increasing temperature between 30°C-60°C. The results show that using finer carrier particles improves the performance of K-nZVI for removing Pb(II) in aqueous solutions.
