Synthesis and characterization of C-doped TiO2 thin films for visible-light-induced photocatalytic degradation of methyl orange

A novel biotemplated synthesis of TiO2/wood charcoal composites for synergistic removal of bisphenol A by adsorption and photocatalytic degradation

“…The peak at 286.4 eV is assigned to C-O-C or C-O-H. Moreover, no signal for C in the lattice of TiO 2 (BE=288.6 eV) was observed from the XPS spectrum of TiO 2 -WC-450 composite [52,53]. Therefore, it can be easily concluded that the oxygen in TiO 2 lattice is not substituted by C element.…”

Nanoscale TiO2 films and their application in remediation of organic pollutants

“…However, they can potentially agglomerate in their suspension form thus reducing their activity as well as their potential for recyclability. Further, the suspended TiO 2 nanoparticles impose health hazards due to their potential nanotoxicity, as nanoscale TiO 2 powders are not easily recoverable from the solution after water treatment [89]. In addition, it has been suggested that penetration depth of light is limited because of strong absorption by both, the catalyst nanoparticles and dissolved organic species [65].…”

Multifunctional titanium oxycarbide films fabricated by filtered cathodic vacuum arc technique using CO2 as a precusor

“…The E ind g value is calculated to be 3.2 eV for films deposited under 45 sccm, and 3.3 eV under 55 sccm, which are close to the C-TiO 2 (3.0 eV) and pure TiO 2 (anatase, cal. 3.2 eV) reported by Mohamed Elfatih Hassan et al [18]. The as-reported result indicates the films have great potentials in photocatalytic and optoelectronic applications.…”

“…As shown in Raman spectra, the peak around 1575 cm À 1 corresponding to G peak, originates from lattice vibrations in the plane of the graphite-like rings, and the peak around 1350 cm À 1 , corresponding to D peak, is due to the disorder-allowed zone edge mode of graphite [18]. The D peak and G peak in Raman spectra of films which are deposited under a high CO 2 gas flow rate (Z55 sccm) (as shown in Fig.…”
