Preparation, characterization, and photocatalytic activity of boron doped TiO2-CNTs nanocomposites |
| 초록 |
Nanosized TiO2 and CNTs are important functional materials that have received considerable research interest in the last few decades. In this work, the B doped TiO2–CNTs nanocomposites with different mole% doping of boron were prepared by using a solution-based method. The various physicochemical properties of synthesized nanocomposites were studied in connection with photodegradation of methylene blue dye solution. Nanocomposites have non-spherical shape with size in the range of 11–15 nm; which were confirmed through XRD and TEM analysis and these nanoparticles were well hosted on the surface of CNTs. Raman analysis confirmed the presence of pure anatase phase in nanocomposites. The tuning the optical band gap of nanocomposites was studied by using UV-visible diffused reflectance spectroscopy. X-ray photoelectron spectroscopy was used to determine the surface compositions of the nanocomposites. The photodegradation of MB indicated that the photocatalytic activity of pure TiO2 nanoparticles increased with increasing boron concentration up to 3 mole% Overall, the experimental results suggest that 3 mole % B doped TiO2-CNTs nanocomposites have been developed as an efficient photocatalyst for removal of organic pollutant in the environment. |
