Tin was deposited in the amount of 0.4 and 0.8 nm onto CeO2(111) surface by molecular beam deposition at the temperature of 520 K. The interaction of tin with cerium oxide was studied with use of XPS, UPS and RPES (Resonant Photoelectron Spectroscopy). The strong tin – ceria interaction led to the Ce(4-nx)+Snxn+O22compound formation. It was accompanied with partial reduction of CeO2 observed as...

SnO2 nanocrystals were prepared by precipitation in dodecylamine at 100 °C, then they were reacted with vanadium chloromethoxide in oleic acid at 250 °C. The resulting materials were heat-treated at various temperatures up to 650 °C for thermal stabilization, chemical purification and for studying the overall structural transformations. From the crossed use of various characterization technique...

Boron- and cerium-codoped TiO2 photocatalysts were synthesized using modified sol-gel reaction process and characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), particle size distribution (PSD), diffuse reflectance spectra (DRS), and Brunauer-Emmett-Teller (BET). The photocatalytic activities were evaluated by monitoring the degradation of dye Acid Red B (ARB). The r...

Copper oxide (CuO)-decorated cerium oxide (CeO₂) nanoparticles were synthesized and used to detect glucose non-enzymatically. The morphological characteristics and structure of the nanoparticles were characterized through transmission electron microscopy, X-ray photoelectron spectroscopy, and X-ray diffraction. The sensor responses of electrodes to glucose were investigated via an electrochemic...

To evaluate the significance of thin-film composite membrane surface morphology on water productivity, flat-sheet experiments were conducted with silicon dioxide, titanium dioxide, and cerium dioxide nanoparticles. The polyamide thin-film active layer exhibited a valley and ridge morphology that was directly related to the surface roughness, and was found to contribute to particle accumulation ...

Electrostatically stabilized monolayer shells of metal-oxide cluster anions (polyoxometalates, or POMs) on the surfaces of ca. 8 nm tetrahedral and octahedral gold nanocrystals regioselectively direct water-soluble alkanethiolate ligands to the corners and edges of the gold polyhedra.
