Crystallite size and lattice strain at peak broadening of TiO2 nanoparticles were studied using Williamson–Hall analysis and Scherrer's equation. It was found that W–H crystallite sizes were significantly different from the sizes obtained from Scherrer's equation at basic medium (pH 8–12) under...
The successful interface between TiO2 and rGO was confirmed by the broadening characteristic of the XRD peak for anatase TiO2, increasing D and G band intensity ratios (ID/IG) of Raman spectra from 1.05 to 1.9, and decreasing intensity of UV–Vis transmittance spectra as the rGO concentration ...
