Aminosilane Modified Clay Nanotubes as a Template for Visible Light Active Ru/CdS Photocatalysts

Prokaryotic and eukaryotic toxicity of halloysite decorated with photoactive nanoparticles

“…12 CuS nanoparticles could be synthesized on the surface of halloysite modified with aminosilanes and azines of various compositions using methods similar to CdS NPs stabilization on clay nanotubes. 75–77 Our preliminary studies showed that depending on the modification agent (aminosilane or ketazine) CuS NPs stabilized on nanotubes possess different antibacterial activity under visible light against S. aureus . Halloysite modification could be applied to change the charge and chemistry of clay tubes and tune the structure and activity of nanomaterials based on it.…”

CdS Quantum Dots in Hierarchical Mesoporous Silica Templated on Clay Nanotubes: Implications for Photocatalytic Hydrogen Production

“…Inorganic supports play a key role in building up nanostructured catalysts capable of industrial application . Due to the availability of clay minerals, as well as opportunities for their chemical modification, these materials have been studied as prospective supports for photocatalytic nanoparticles. − TiO 2 , g-C 3 N 4 , ZnO, CdS, and MoS 2 are among the most efficient semiconductors and have been supported on clay minerals. ,, Tubular clays such as halloysite are characterized by better catalytic activity in photocatalytic reactions, compared to platy ones due to the higher dispersibility in reaction media, higher surface area, and additional possibility of placing active sites inside clay nanotubes. , To achieve better photocatalytic results, modification of clay tubes was performed prior to the stabilization of nanoparticles. − Grafting of aminosilanes and organic ligands on the surface of clays led to efficient photocatalysts. ,, The tailored design of new supports and optimization of the composition and the structure of catalysts are some strategies applied for enhancing the photocatalytic efficiency . However, this approach has not been fully transferred to the nanoarchitectonics of photocatalytic systems, yet.…”
