Preparation of siloxy focal dendron-protected TiO2 nanoparticles and their photocatalysis

Ag nanoparticle-immobilized cellulose nanofibril films for environmental conservation

“…After the addition of AgNPs, Fermi potential of the metal particles decreases, the potential difference of BH 4 − and dye diminishes, and hence the electron transfer may occur easy through AgNPs. Meanwhile, the coexistence of dendrimer in the catalytic system may accelerate the catalytic reaction: Ag catalystcoating dendrimer can play a role as an adsorbent and a reservoir of guest molecule to increase its number on the surface of catalyst [38][39][40]. The schematic mechanism is shown in Fig.…”

Sensitizing of pyrene fluorescence by β-cyclodextrin-modified TiO2 nanoparticles

“…Then the solution of the b-CD-modified TiO 2 nanoparticle was almost transparent (water-soluble) and very stable owing to too small size and enough protection by b-CD. Similar water-dispersible TiO 2 nanoparticles have been prepared using water-soluble dendrimers in place of b-CD [10,11].…”

“…Among the nanometer-sized semiconductors, TiO 2 is widely investigated because of its potential use in photovoltaic cells, batteries, sensing, optical emissions, photonic crystals, catalyses, photocatalyses, ion exchange, ultraviolet blockers and energy storages [4][5][6][7][8]. Thus, the controlled synthesis of TiO 2 nanoparticles with defined size and morphology would generate significant opportunities for applications [9][10][11].…”

Preparation of Hollow Titania Nanoparticles of Single-nanometer Size Using a PAMAM Dendrimer Template

“…uniform molecular size and chemically modifiable terminal groups 24 . Regarding the dendrimer-assisted synthesis of titania nanoparticles, Imae and co-workers 25,26 reported poly amidoamine PAMAM dendrimersprotected titania nanoparticles using TiCl 4 as a precursor, as well as their photocatalytic properties for the photodegradation of an organic pollutant. Each titania nanoparticle was protected with several dendrimer molecules, and thus, the role of dendrimers was not being a template but a stabilizer for titania nanoparticles.…”
