“…In another batch adsorption study carried out by Feng et al, mesoporous MgO nanosheets were prepared (Scheme 3.) and they exhibited extraordinary removal capacity towards Ni (II) with the value of 1684.25 mg·g −1 calculated from the Langmuir model [205]. The pseudo-second-order model fitted the adsorption kinetic well.…”

Removal of contaminants in wastewater, such as heavy metals, has become a severe problem in the world. Numerous technologies have been developed to deal with this problem. As an emerging technology, nanotechnology has been gaining increasing interest and many nanomaterials have been developed to remove heavy metals from polluted water, due to their excellent features resulting from the nanometer effect. In this work, novel nanomaterials, including carbon-based nanomaterials, zero-valent metal, metal-oxide based nanomaterials, and nanocomposites, and their applications for the removal of heavy metal ions from wastewater were systematically reviewed. Their efficiency, limitations, and advantages were compared and discussed. Furthermore, the promising perspective of nanomaterials in environmental applications was also discussed and potential directions for future work were suggested.

“…11 shows the high 14 resolution TEM images of E. coli treated with spherical and hierarchical TiO 2 /Ag composites, respectively. Compared with isotropy of spherical composite (Fig 11a), the hierarchical composite with nano-needle units had bigger effective target area (Fig 11b) and stronger penetration capability towards bacteria, which caused seriously damage of the cell membranes [42] .…”

ABSTRACT:A spherical titanium dioxide/silver (TiO 2 /Ag) composite and a flower-like hierarchical TiO 2 /Ag composite were prepared via a template-induced method and a solvothermal method based on the Ag/Carbon spheres templates followed by calcination treatment, respectively. The morphologies of the composites were controlled by changing the concentration of reactants and calcination temperature. The antibacterial efficiency of the composites was evaluated with both Gram-negative Escherichia coli and 2 species (ROS) and silver ions were observed, which lead to superior antibacterial activities of these TiO 2 /Ag composites with a bacteriostatic rate as high as 99% even in the absence of light. The morphological effect of the composites on the antibacterial efficacy was also investigated. In addition, a durable antimicrobial coating was also fabricated by incorporating the hierarchical TiO 2 /Ag composite into a commercial emulsion solution of polyvinyl acetate, which exhibited a promising application in bacterial sensitive locations.

“…Particularly, nanosized MgO has exhibited higher efficiency and faster adsorption rate in wastewater treatment, owing to its higher surface areas and much more surface active sites than bulk materials. Feng et al [16] reported mesoporous MgO nanosheets had the maximum adsorption capacity of 1684.25 mg/g for Ni(II) removal from aqueous solutions.…”
