Photoluminescent hybrid nanomaterials from modified halloysite nanotubes
2018
The synthesis of photoluminescent nanomaterials based on halloysite nanotubes is described. The obtained hybrid was characterized by means of TGA, FT-IR, DLS and XPS measurements; in addition its morphology was imaged by TEM and HR-TEM. The HNT hybrid also exhibited photoluminescent properties, both in solution and in the solid state, and white-light emission (0.24, 0.36; CIE coordinates) was observed. This work could be pioneering as a new strategy for manufacturing both LEDs and fluorescent tags based on HNT nanomaterials. © 2018 The Royal Society of Chemistry.
Magnetic hybrid nanomaterials for the photodegradation of microcontaminats in aqueous environment
2018
Bio-based substances (BBS) isolated from urban biowaste have been employed to prepare hybrid magnetic nanomaterials with iron oxides. Such materials have been tested, in the presence of hydrogen peroxide, for the light induced photodegradation of four microcontaminants (MCs) in aqueous environment: Carbamazepine (C, an anticonvulsant and analgesic drug), Flumequine (F, an antibiotic), Ibuprofen (I, a non-steroidal anti-inflammatory drug), and Sulfamethoxazole (S, an antibiotic). Preliminary photodegradation experiments were carried out at lab-scale in a solar simulator, whereas optimized experiments were carried out in a pilot plant under natural solar radiation. The MCs complete abatement …
