Abstract
Nanomaterials exhibit promising performance in water decontamination via adsorption, catalytic degradation, and other processes. However, the ultrafine particle size also brings issues including excessive pressure drop in flow-through systems and environmental risk arising from nanoparticle release. To overcome the bottleneck of most nanomaterials in full-scale manipulation, a series of millimetre-sized nanocomposites have been developed via in situ formation of nanoparticles (e.g. metal oxides/hydroxides/phosphates) confined in the pore channels of ion exchanger hosts. Such nanocomposites are suitable for application in fixed-bed reactors owing to their tunable size (0.6-1.0 mm) and excellent hydrodynamic properties. The confinement effect induced by the network pore structure of the cross-linked hosts tend to maintain the nanoscale nature of the embedded nanoparticles. Furthermore, the non-diffusible charges fixated on the host skeleton enhance the permeation of ionic pollutants inside the pore channels. Thus, the polymer-supported nanocomposites have demonstrated favorable adsorption of ionic pollutants such as Pd(II), Cd(II), Cu(II), As(V), F-, P(V), and have been successfully applied in full-scale advanced water treatments. Recently, novel millimeter-sized nanocomposites of inorganic skeleton (e.g. Ce-Ti-Zr ternary oxide) have been developed for catalytic oxidation processes, and have showed satisfactory performance in mineralization of recalcitrant pollutants such as oxalic acid.
