The mechanism of phenol degradation was also investigated by high-performance liquid chromatography, X-ray diffraction, and UV-vis spectrum.doi:info:doi/10.1080/19443994.2015.1033471Danlin ZengShenglan LiuQi ZhangGuanghui WangYang ChenYongsheng Tian...
IR (Fourier Transform Infrared), DR UV-Vis (Diffused Reflectance Ultraviolet Visible), XRD (X-ray diffraction), SEM(scanning electron microscope), TEM (Transmission Electron Microscope), XPS (X-ray photoelectron spectroscopy), ICP (inductively coupled plasma spectrum), and N2 adsorption-desorption. ...
Structural analyses were carried out by powder X-ray diffraction and Fourier transform infrared spectrum to conform the grown crystals. Thermal stability of the grown crystals was studied by thermogravimetric (TG) and differential thermal analyses (DTA). UV–vis spectral analysis has been carried out...
1A). The 1H NMR spectrum of Chi-Ph showed peaks at 6.8 and 7.1 ppm, confirming effective conjugation of phenol groups (Fig. 1B). In UV–Vis spectra, Chi-Ph exhibited an absorbance peak at 275 nm, while such peak was not detected for chitosan (Fig. 1C). The peak of 275 nm was ...
Moreover, the peak observed at 1613 cm−1 changed from lower intensity peak in the IR spectrum of raw POF to higher intensity peak in the IR spectrum of NaOH-treated POF [32–34]. Compared to the FT-IR spectrum of NaOH-treated POF (Figure 1(b)), the FT-IR spectrum of CTAB-...
The presence of N–H bending of the amides group is indicated in the region of 1035–1050 cm−1. Fig. 3 FTIR spectrum: a raw rice husk; b RHAC Full size image Effect of process parameters on breakthrough curves Effect of flow rate The experiments for the effects of flow rate on ...

However, TiO2 is a wide bandgap material absorbing only UV light of the solar spectrum. Further, the instantaneous recombination of photogenerated electrons with holes in TiO2 affects its catalytic activity. These are the two major drawbacks of TiO2 photocatalysts. Therefore, much research has been ...
The photocatalysts were characterized by Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), Raman spectrum and UV-Vis (Ultraviolet-Visible) spectrometry techniques, and the photocatalytic activity in phenol-contaminated water was investigated. The results showed that photocatalysts calcined at 400 ...
