A study of the infrared absorption spectra of thin amorphous films of molybdenum trioxide
(1989)
The spectra of thin amorphous films of MoO3 deposited by vacuum evaporation have been studied within the spectral range 4000-400 cm-1 by the Fourier transform infrared technique. Some samples in the thickness range 100 to ...
Investigation of infrared absorption spectra of copper phosphate glasses containing some rare earth oxides
(1990)
The spectra of copper-lutetium-phosphate and copper-erbium-phosphate glasses have been studied within the spectral range 4000 to 400 cm- by Fourier transform infrared spectroscopy. Incorporation of a small amount of lutetium ...
Infrared spectra of some thin amorphous films of MoO3-In2O3 deposited by vacuum evaporation
(1989)
The infrared absorption spectra of vacuum-evaporated MoO3-In2O3 thin films are reported for a series of films of varying compositions within the spectral range 4000 to 400 cm-1 and interpreted in relation to the spectrum ...
Infrared spectroscopic study of vacuum evaporated amorphous thin films of MoO3-SiO
(1990)
A series of amorphous MoO3-SiO thin films of varying compositions were investigated by infrared spectroscopy. In some cases, a shift in band frequency was observed. Some new peaks appeared when SiO was mixed in MoO3. These ...
Temperature programmed reduction of silica supported nickel catalysts
(1993)
Nickel oxide promoted catalysts are prepared by simple precipitation, precipitation from homogeneous solution and impregnation methods and their reduction behavior is monitored with temperature programmed reduction (TPR) ...
Preparation and surface characterisation of novel ceria-copper and ceria-manganese mixed oxides
(2002)
The paper presents surface texture and catalysis results for a series of copper and manganese-containing ceria samples. These samples, especially the 20% manganese containing one, had significantly higher surface area than ...
Modified aluminophosphate molecular sieves: preparation and characterisation
(1988)
Crystalline microporous aluminium phosphate has been prepared in a variety of ways. The influence of the preparative conditions affecting the solid state properties of the resultant solids were studied. Quencg cooling of ...
The efficient removal of organic templating molecules from aluminophosphate molecular sieves
(1986)
Treatment with methanolic HCl leads to the complete removal of templating molecules from the title solid
Preparation and characterization of nanoporous ternary mixed cerium oxides
(2006)
We report the synthesis and characterisation of ceria samples containing two heteroatoms, namely vanadium and copper or iron. For certain compositions, the samples contained both micropores and mesopores. High BET surface ...
The effect of surface properties on the uranium adsorption by mesoporous ceria
(2018)
CeO2 solids of different surface areas have been prepared by a sol–gel method using Triton X-100. The samples have then characterized by N2 adsorption, XRD, SEM microscopy and FTIR spectroscopy. Furthermore, the effect of ...
