One step syntheses of S incorporated ZnO nanowires for photocatalysis applications
S incorporated ZnO nanowires (NWs) were prepared by vapor transport method using ZnS bulk precursor. Effects of S incorporation on the structural, morphological, optical as well as photocatalysis performance of ZnO NWs were studied. EDAX analysis revealed existence of S with low ratio. A deformation of the hexagonal nanowires was observed inasmuch to the S existence. X-ray diffraction analysis asserted ... Read more

Acidic Peptizing Agent Effect on Anatase- Rutile Ratio and Photocatalytic Performance of TiO2 Nanoparticles

Acidic Peptizing Agent Effect on Anatase- Rutile Ratio and Photocatalytic Performance of TiO2 Nanoparticles
TiO2 nanoparticles were synthesized from titanium isopropoxide by a simple peptization method using sulfuric, nitric, and acetic acids. The effect of peptizing acid on physicochemical and photocatalytic properties of TiO2 powders was studied. The structural properties of synthesized TiO2 powders were analyzed by using XRD, TEM, N2-physisorption, Raman, DR UV-vis, FTIR, and X-ray photoelectron spectroscopy techniques. The characterization results showed ... Read more
