“…Kaolinite has exceptional crystal chemical features. Therefore, it could act as a suitable matrix for anchoring TiO 2 and ZnO nanoparticles (Dědková et al 2015;Hadjltaief et al 2017). Immobilizing and anchoring nanosized TiO 2 and ZnO nanoparticles on the surface of clay minerals provide more active surface sites, reduces the agglomeration of the nanoparticles, and prevents the release of nanoparticles into the environment.…”

Increase in industrial and anthropogenic activities leads to a decline in water quality. This necessitates the need for the removal of contaminants from industrial and domestic wastewater. Clay minerals are naturally abundant and non-toxic materials that found to be useful for remediation of emerging contaminants from wastewater. This review paper presents an insight into clay, the simplest material (in solgel techniques) for the synthesis of TiO 2 and ZnO, mechanisms of their reactions, analytical techniques used for characterizations, and their nanocomposites for wastewater treatment. Nanomaterials, such as nanoclay, titanium, and zinc oxide, have offered the opportunities of sequestering variety of pollutants in wastewater. TiO 2 and ZnO anchored on clay have been found to be good promising sequesters and have been explored for wastewater remediation via nanotechnology. This water treatment method includes adsorption/absorption, photocatalysis, and microbial disinfection. These nanocomposites provide more active surface sites and reduce the agglomeration of the nanoparticles, but leaching has been their shortcomings. To overcome this, the filtration technique may become significant for the removal and avoidance of fouling of wastewater. This can be achieved through the fabrication of nano-based filters using the nanocomposites.

“…2 (c)), which is evident that the higher crystallinity in the milled powders. The obtained XRD peaks matched with SiC JCPDS card number 00-1129-23 [29] and Copper JCPDS card number 00-003-1018 [30]. No diffraction peaks were observed in the XRD except Cu and SiC which indicates that the composite powders were not undergone oxidation during ball milling.…”

Spark plasma sintering (SPS) is a novel approach to fabricate Cu-SiC composites which have a relatively broad range of potential uses in space applications. The Cu-4wt% SiC composite with homogeneously dispersed SiC particles has been successfully synthesized at various SPS temperatures. In this study, the effect of SPS temperatures on the phase evaluation and mechanical characteristics of the Cu-4wt% SiC composite was investigated. From the results, it was con rmed that the optimum sintering temperature for Cu-4wt% SiC composite is 950 ℃. Raising the spark plasma sintering temperature from 850 ℃ to 950 ℃ led to a higher concentration of copper-liquid phase which accelerates the SiC particle rearrangement and lls the interstitial voids present in the interfaces of matrix and reinforcements which improves the mechanical properties of the Cu-4wt% SiC composite. However, increasing the SPS temperature by more than 950 ℃ prone to the generation of the copper net and inhomogeneous SiC particle dispersion in the copper phases and declines the performance characteristics of the synthesized composite. The Cu-20wt% SiC composite sintered at 950 ℃ exhibits superior mechanical characteristics than the composite sintered at 850 ℃, 900 ℃ and 1000 ℃.
