Influencing surface phenomena by Au diffusion in buffered TiO2-Au thin films: Effects of deposition and annealing processing

Effect of the Photoreduction Process on the Self-Cleaning and Antibacterial Activity of Au-Doped TiO2 Colloids on Cotton Fabric

“…The peaks related to Ti 2p 3/2 and Ti 2p 1/2 appeared at 458.78 and 464.58 eV, respectively, which are in good agreement with the literature . These peaks corresponded to Ti 4+ bonds and proved the existence of TiO 2 on the surface . The detected Au 4f 7/2 peak at 83.3 eV confirmed the presence of metallic Au clusters on the coated surface; however, this peak could hardly be detected on the samples coated with colloids containing ionic gold .…”

“…55 These peaks corresponded to Ti 4+ bonds and proved the existence of TiO 2 on the surface. 56 The detected Au 4f 7/2 peak at 83.3 eV confirmed the presence of metallic Au clusters on the coated surface; however, this peak could hardly be detected on the samples coated with colloids containing ionic gold. 57 The C 1s peak in pristine cotton appeared as two main peaks at 284.78 and 286.28 eV, which were related to C− C and C−H bonds, and the C−O bond of cellulose, respectively.…”

“…After applying TiO 2 -based colloids, the peak intensity at 284.78 eV increased, which can be attributed to the formation of C–C bonds and the acetic acid . Pristine cotton showed the O 1s peak at 532.68 eV, while two peaks at 530.18 and 532.68 eV appeared for treated fabrics, ascribed to TiO 2 ’s lattice oxygen atoms and surface hydroxyl group (Ti–OH), respectively. , After adding SiO 2 , the O 1s peak intensity at 532.68 eV sharply increased, and the peak at 102.88 eV derived from the Si–O–Si bond appeared . The increase of peak intensity at 532.68 eV is ascribed to the formation of Si–O–Si and Ti–O–Si bonds and hydroxyl groups from the surface .…”
