“…Sci. 2017, 7, 1284 10 of 12 adsorption capacity of the TiO2/Al2O3 composite membrane arises mainly from complementary cavities and rebinding sites on the membrane assisted by the POEM template [26]. The advantages of the presence of such a well-organized TiO2 film were further observed upon carrying out the membrane filtration under UV illumination (Figure 9b).…”

Photocatalytic ceramic membranes have attracted considerable attention for industrial wastewater treatment. However, morphological control of the membrane surface to improve its photocatalytic reactivity for the degradation of organic pollutants remains a challenge. Herein, we report a new nanostructured TiO 2 /Al 2 O 3 composite ceramic membrane prepared from a poly(oxyethylene methacrylate) (POEM) template through a sol-gel method and its photocatalytic performance in the treatment of a model dye compound. The POEM polymeric template allowed the homogeneous distribution of catalytic sites, i.e., the TiO 2 layer, on the Al 2 O 3 membrane surface, resulting in improved organic dye degradation along with effective fouling mitigation. The immobilization of a TiO 2 layer on the Al 2 O 3 membrane support also significantly enhanced the membrane adsorption capacity toward dye organic compounds. An organic removal efficiency of over 96% was achieved with the TiO 2 /Al 2 O 3 composite membrane under Ultraviolet (UV) irradiation. In addition, the self-cleaning efficiency of the TiO 2 /Al 2 O 3 composite membrane was remarkably improved by the degradation of organic foulants on the membrane under UV illumination.

Kaolin/calcium alginate (kaolin/CaAlg) free-standing membranes were prepared by adding different amounts of Kaolin into the sodium alginate (NaAlg) casting solution and crosslinked by Ca2+ using urea as porogen agent. The morphology of the kaolin/CaAlg filtration membrane was characterized by scanning electron microscope (SEM). Then the kaolin/CaAlg membrane was used for the removal of dyes and Cd2+. The kaolin significantly improved the mechanical behavior and flux of the kaolin/CaAlg membrane. The flux reached 17.53 L/m2·h at 0.1 MPa and when the content of Kaolin in NaAlg was 70 wt.%. The filtration of BSA solution and oil-water emulsion indicated that the kaolin/CaAlg composite filtration membrane exhibited good anti-fouling properties. The rejection of Brilliant Blue G250, Congo red, and methylene blue by the kaolin/CaAlg filtration membrane was 100%, 95.22%, and 62.86%, respectively. The removal rate of Cd2+ reached 99.69%, with a flux of 17.06 L/m2·h at 0.1 MPa.

“…[1][2][3][4][5][6][7][8][9][10] Owing to the surface location of the nanosized cavities, the surface imprinting technique has become one of the most effective ways to improve the preparation of molecularly imprinted polymers (MIP). The formation of cavities is based on the formation of a prepolymerization complex initially containing a template molecule and monomer.…”

Surface molecularly imprinted (MIP) poly [N-(2-hydroxypropyl) methacrylamide] [poly(HPMA)] films were prepared via interface-mediated reversible addition-fragmentation chain transfer (RAFT) polymerization from 4-cyano-4-(propylsulfanylthiocarbonyl) sulfanyl pentanoic acid immobilized silicon substrate using N-(2-hydroxypropyl) methacrylamide as the functional monomer, N,N 0 -methylene(bis)acrylamide as the crosslinking agent, and ibuprofen as the template molecule. The highly crosslinked MIP layer (12 nm) was homogeneously grafted onto the silicon surface, which favors fast mass transfer and rapid binding kinetics. Binding capacities and adsorption parameters of the MIP poly(HPMA) films were calculated from the root-mean-square roughness data obtained by atomic force microscopy measurements using the Luzinov and Langmuir equations adopted for this study. The target binding assays demonstrate the desirable binding capacity and imprinting efficiency of the MIP poly(HPMA) films. Meanwhile, the computational optimization and energy calculations showed the formation of the self-assembly of monomer and template molecule via noncovalent interactions that leads to a 1:4 molecular complex between ibuprofen and N-(2-hydroxypropyl) methacrylamide. This study provides a versatile approach to the quantitative determination of low-molecular-weight biomolecules on surfaceimprinted polymers.
