Jul 18, 2012 · A surface science approach to TiO2 P25 photocatalysis: An in situ FTIR study of phenol photodegradation at controlled water coverages from sub-monolayer to multilayer.

Jul 6, 2020 · A HRTEM image of a nanoparticle exposing regular and sharp edges with well-defined interference fringes is shown in Figure 2H. The observed fringes are compatible with rutile (011) and (101) lattice planes as imaged from [−111] zone axis (Figure 2I).

The photocatalytic process for degradation of methylene blue with P25 TiO 2 was directly observed using a high-resolution transmission electron microscopy (HRTEM).

Feb 19, 2012 · In the present work, we prepared highly active TiO 2 powder photocatalyst via calcination after treatment of Degussa P25. The photocatalytic activity of the as-prepared TiO 2 powders was evaluated by the photocatalytic oxidation of methyl orange aqueous solution under UV light irradiation in air.

X-ray photoelectron spectroscopy analysis reveals the interstitial incorporation of boron into the surface lattice of the TiO2 nanostructure, while segregation of B2O3 occurs in samples with high...

The photocatalytic process for degradation of methylene blue with P25 TiO 2 was directly observed using a high-resolution transmission electron microscopy (HRTEM).

The P25 powders before and after calcination treatment were characterized with XRD FTIR, UV-visible diffuse reflectance spectra, SEM, TEM, HRTEM, and N2 adsorption-desorption measurements.

Jul 15, 2007 · HRTEM images showed that the implanted V ions existed in the form of VO 2 (T) in the lattice of P25 TiO 2. The intensity of photoluminescence (PL) spectra of V-ion-implanted P25 TiO 2 decreased with the increase of the amount of implanted V ions, indicating the decrease of electron–hole pair recombination.

Highlighted also in the following HRTEM images (Figure 3a,b), we can ascribe the observed features to interference fringes of MoS 2 layers or dots covering the TiO 2 n-sh and TiO 2 bipy...

Jul 7, 2020 · Shape-controlled TiO2 nanoparticles and TiO2 P25 interacting with CO and H2 O2 molecular probes: a synergic approach for surface structure recognition and physico-chemical understanding.
