Visible light responsive Bi₂S₃-graphene/TiO₂ nanocomposites: one pot-hydrothermal synthesize and improved photocatalytic properties

Robust self-cleaning effects of cotton fabrics coated with reduced graphene oxide (RGO)-titanium dioxide (TiO2) nanocomposites

“…Both microstructure and self-cleaning performance of the resultant RGO-TiO 2 nanocomposite coating immobilized on the surface of cotton fabrics were analyzed. The results of FESEM, AFM, XRD, Raman, particle size distribution, BET, TEM, and XPS verified that anatase TiO 2 nanoparticles were successfully incorporated with GO nanosheets to form the RGO-TiO 2 nanocomposite particles, which were chemically grafted with cotton fabric via the bonds of C-Ti 4 ( 3 )+ 2p3/2 /O-Ti 4 ( 3 )+ 2p3/2 and C-Ti 4 ( 3 )+ 2p1/2 /O-Ti 4 ( 3 )+ 2p1/2 . The as-synthesized anatase TiO 2 nanoparticles were not only immobilized on cotton fiber surfaces but also infiltrated into the substrate of cotton fibers.…”

“…The binding energies at 453.69 eV and 460.36 eV were respectively assigned to the C-Ti 3+ 2p3/2 /O-Ti 3+ 2p3/2 and C-Ti 3+ 2p1/2 /O-Ti 3+ 2p1/2 bonds. As a result, it was concluded that RGO-TiO 2 composites were chemically grafted with cotton fabric via the C-Ti 4 ( 3 )+ 2p3/2 /O-Ti 4 ( 3 )+ 2p3/2 and C-Ti 4 ( 3 )+ 2p1/2 /O-Ti 4 ( 3 )+ 2p1/2 bonds.…”

“…2 Especially, the delocalized electrons of its carbon network impart graphene with excellent electron conductivity (200,000 cm 2 /V·s). 3 The high electron mobility and π-π conjugation structure of graphene make it an ideal electron acceptor and good electron transporting bridge. 4 Moreover, graphene can be chemically modified with hydroxyl, carboxyl, and epoxy functional groups.…”
