چکیده

This research demonstrates a simple method for synthesizing titanium dioxide nanoparticle-decorated carbon nanofibers. These nanofibers showed highly efficient degradation of methylene blue under UV light because of the synergistic effects of the large surface-active sites of titanium dioxide nanoparticles and the carbon nanofibers on the photocatalytic properties.

Defective TiO2 with oxygen vacancies: synthesis, properties and photocatalytic applications.

Titanium dioxide (TiO2), as an important semiconductor metal oxide, has been widely investigated in the field of photocatalysis. The properties of TiO2, including its light absorption, charge transport and surface adsorption, are closely related to its defect disorder, which in turn plays a significant role in the photocatalytic performance of TiO2. Among all the defects identified in TiO2, oxy...

Enhanced visible-light photocatalytic performance of electrospun carbon-doped TiO2/halloysite nanotube hybrid nanofibers.

In this work, the effects of halloysite nanotubes (HNTs) on the visible-light photocatalytic ability of electrospun carbon doped TiO2/HNT (C-TH) nanofibers have been explored. Structural and morphological investigations demonstrate that incorporation of HNTs into anatase C-TH hybrid nanofibers was easily achieved by using sol-gel processing combined with electrospinning approach, thus HNTs coul...

THE ACTIVATION OF CARBON DIOXIDE AT A MAGNESIUM (1 00) SURFACE THE ROLE OF OXYGEN TRANSIENTS

X-ray photoelectron and high resolution electron energy loss spectroscopic (XPS-HREELS) studies have shown that the adsorption of carbon dioxide at Mg(100) surfaces at 80K is followed by a dissociative reaction leading to the formation of a metastable surface carbonate above 80K. The formation of a carbonate species is proposed to proceed through oxidation of C0 (g) by an active oxygen su...
