“…The major peaks at 25. composites existed in anatase crystal phase. As we known, the anatase phase formed below 773 K starts to transform to rutiletype structure above 873 K and changed into single phase of rutile at 973 K-1173 K. 21) The result is in accordance with, 22) so the results of XRD in this paper are reasonably. The micro-surface structures and morphology of CNT/TiO2 composites prepared with different concentration TNB solution were characterized by SEM and FE-SEM.…”

In this study, we have prepared three kinds of carbon nanometer tube (CNT)/TiO2 electrodes through impregnation with different concentration titanium n-butoxide (TNB) solution. The prepared electrodes were characterized with surface properties, structural crystallinity, elemental identification and photoelectrocatalytic activity. The N2 adsorption data showed that the composites had decreased surface area compared with the pristine CNT. This indicated the blocking of micropores on the surface of CNT, which was further supported by observation via SEM. XRD results showed patterns for the composites and a typical single and clear anatase crystal structure. The main elements such as C, O and Ti were existed for all samples from the EDX data. The catalytic efficiency of the developed electrode was evaluated by the photoelectrodegradation of methylene blue (MB). The positive potential applied in photoelectrocatalytic (PEC) oxidation was studied. It was found that photoelectrocatalytic (PEC) decomposition of MB solution could be attributed to combination effects between TiO2 photocatalytic and CNT electro-assisted. Through the comparison between photocatalytic (PC) oxidation and photoelectrocatalytic (PEC) oxidation, it was found that the PEC oxidation efficiency for MB is higher than that of PC oxidation.

“…An important step in the photocatalytic process is the adsorption of reacting substances onto the surface of the catalyst. ACF has a welldeveloped pore structure, very large surface area about 967.4 m 2 /g 25) and strong adsorption capacity and is widely used as an adsorbent and catalyst support.…”

Activated carbon fiber (ACF) was modified with MnS nanoparticles to prepare MnS-ACF, and it was employed for preparation of MnS-ACF/TiO 2 composites with titanium (IV) n-butoxide (TNB). The properties of MnS-ACF/TiO 2 composites were characterized by XRD, SEM, and EDX. EDX results showed the presence of C, O, and Ti as major elements and traces of the metal elements Mn and S. The photocatlytic activity was evaluated by degradation of methyl blue (MB) and methyl orange (MO) dye. The results demonstrated that as-prepared samples could effectively photodegrade MB and MO under UV irradiation. Subsequently, the decomposition of MB solution showed the combined effects of adsorptions by ACF and enhanced photocatalytic effect by TiO 2 . Finally, the photocatalytic effect increased due to photo-induced-electron absorption effect by ACF and electron trap effect by comodified MnS nanoparticles.
