Nanoporous polymer monoliths as adsorptive supports for robust photocatalyst of Degussa P25

In situ immobilization of tin dioxide nanoparticles by nanoporous polymers scaffold toward monolithic humidity sensing devices

“…Finally, composite materials formed and SnO 2 NPs were immobilized homogeneously in the matrices of nanoporous polymeric scaffold after evaporation of the solvents. The nanoporous structure formed during the solvothermal polymerization due to the presence of porogenic solvent has been reported previously [28][29][30]. It is noteworthy that the whole procedure was quite simple and facile, and no undesired by-products were present.…”

“…Previously, we have successfully prepared nanoporous polymers that featured high BET surface area, large pore size and pore volume, revealing outstanding adsorptive properties towards a wide range of compounds [28][29][30][31][32]. In this work, as proof-of-concept, SnO 2 NPs have been post-immobilized within the matrices of the nanoporous polymers scaffold through an in-situ solvothermal polymerization process.…”

Photocatalytic films for soil fumigation: Control of dimethyl disulfide concentration after fumigation

“…11). It should be recalled that most of the previous studies on the photocatalytic efficiency of polymer-TiO 2 composites mainly addressed dye discoloration in solution, such as Orange II [13], Rhodamine B [25], or Methylene blue [26]. Two papers were devoted to gaseous pollutants oxidation: polyethylene terephthalate (PET) embedded TiO 2 was used for gaseous trichloroethylene (TCE) destruction [14], while TiO 2 incorporated in orthophtalic polyester polymers was also efficient for gaseous ethanol mineralization [27].…”

Microwave-Hydrothermal Synthesis of SnO2-CNTs Hybrid Nanocomposites with Visible Light Photocatalytic Activity

“…Some studies on TiO 2 -CNTs composites have proved that the conductive structure of the CNTs facilitates accepting and transferring the light-excited electrons from the conduction band (CB) of the semiconductor to the CNTs surface, which hampered the recombination of the electron-hole pairs [15,16,17,18]. In addition, CNTs as supports would probably promote the catalysts separation during the recycling use compared with solo semiconductor nanoparticles [19]. …”
