Unusual structural phase transition in nanocrystalline zirconia

Preparation of Mn-doped ZrO2/TiO2 photocatalysts for efficient degradation of Rhodamine B

“…It is beneficial to improve of photo-adsorption property, forming interband-gap localized levels to reduce band gap and enlarge specific surface area and the pore volume. [31,32] In order to test the re-use performances of composite photocatalyst, the 0.5% Mn-doped ZrO 2 /TiO 2 photocatalyst is used to take the recycle photocatalytic decoloration of RhB solution, as shown in Fig. 4(b).…”

Strong adsorption of arsenic species by amorphous zirconium oxide nanoparticles

“…1a shows the X-ray diffraction pattern of am-ZrO 2 nanoparticles, compared with that of samples after heat treatment at 450 8C for 1 h. am-ZrO 2 nanoparticles had a very poor crystallization, compared with the well-crystallized samples after heat treatment. Although two major XRD diffraction peaks of tetragonal ZrO 2 phase could be observed in their XRD pattern, the largely widen peaks and weak peak signals indicate that most of these nanoparticles are amorphous [21,[28][29][30]. Fig.…”

Preparation and characterisation of Ag incorporated Al2O3 nanocomposite films obtained by sol‐gel method

“…The broad bands at 3400-3700 cm -1 (not shown here) due to stretching vibrations of hydroxyls bonds appear in the spectra of the two annealing temperatures. It is well known that FTIR spectroscopy is very sensitive measurement technique and can detect small changes in the crystal lattice of the studied compounds [17]. The clear absorption bands appear around 1030 cm -1 for the both types of thin films can be assigned either to Al-OH symmetrical bending mode or to Si-O stretching mode [15].…”
