Heterojunctions of p-BiOI Nanosheets/n-TiO₂ Nanofibers: Preparation and Enhanced Visible-Light Photocatalytic Activity.
p-BiOI nanosheets/n-TiO₂ nanofibers (p-BiOI/n-TiO₂ NFs) have been facilely prepared via the electrospinning technique combining successive ionic layer adsorption and reaction (SILAR). Dense BiOI nanosheets with good crystalline and width about 500 nm were uniformly assembled on TiO₂ nanofibers at room temperature. The amount of the heterojunctions and the specific surface area were well control...
متن کاملVisible light photocatalytic activity of MWCNT/TiO2 using the degradation of methylene blue
Multi-walled carbon nanotubes (MWCNT)-doped TiO2 thin films were synthesized by the dip-coating method. The obtained products were characterized by SEM, EDX, XRD, and UV-vis absorption spectroscopy. The XRD patterns showed the presence of anatase phase. Absorption spectrum of MWCNT-doped TiO2 revealed a red shift in the optical absorption edge due to carbon doping. The photocatalytic properties...

متن کاملNovel heterostructured Bi2S3/BiOI photocatalyst: facile preparation, characterization and visible light photocatalytic performance.
Novel Bi(2)S(3)/BiOI heterostructures were successfully synthesized through a facile and economical ion exchange method between BiOI and thioacetamide (CH(3)CSNH(2)), and characterized by multiform techniques, such as XRD, Raman, FT-IR, XPS, SEM, TEM, HRTEM, SAED, BET and DRS. The obtained Bi(2)S(3)/BiOI photocatalysts showed excellent photocatalytic performance for decomposing organic dye meth...
متن کاملEnhancing Photocatalytic Activity of Nitrogen Doped TiO2 for Degradation of 4-Chlorophenol under Solar Light Irradiation
The nitrogen doped TiO2 as heterogeneous photocatalyst via sol-gel method were successfully synthesized. The physicochemical, morphological and textural characteristics of the obtained TiO2 samples were characterized by advanced analysis techniques. The photocatalytic activity of the samples were evaluated for degradation of 4-CP under solar irradiation. The as-synthesized photocatalysts were c...
