The crystal structures of different forms of TiO2 and those of BaTiO3, ZnO, SnO2, WO3, CuO, Fe2O3, Fe3O4, ZrO2 and Al2O3 nanoparticles have been deduced by powder X-ray diffraction. Their optical edges have been obtained by UV-visible diffuse reflectance spectra. The photocatalytic activities of these oxides and also those of SiO2 and SiO2 porous to oxidize iodide ion have been determined and c...

The morphology-controlled synthesis of SnO2 hollow/nanoporous nanostructures (nanotubes, urchin-like morphologies and nanospheres) was achieved via a template-engaged replacement reaction at a mild temperature (lower than 80 °C). The formation mechanism of hollow interior and nanoporous walls for the obtained SnO2 nanostructures (SnO2 nanotubes were used as an example) was investigated based on...

Pure SnO2 and Y-doped SnO2 nanobelts were prepared by thermal evaporation at 1350 °C in the presence of Ar carrier gas (30 sccm). The samples were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), energy dispersion spectrometer (EDS), X-ray photoelectron spectrometer (XPS), UV-Vis absorption spectroscopy, Raman spectroscopy, and Fourier transform infrared spectrum (F...

Substantial improvement is needed in efficient and affordable decolorization disinfection methods to solve the issues caused by dyes harmful bacteria water wastewater. This work involves photocatalytic degradation of methylene blue (MB) as well gram-negative gram-positive cobalt-doped tin oxide (Co-SnO2) nanoparticles (NPs) Co-SnO2/SGCN (sulfur-doped graphitic carbon nitride) nanocomposites (NC...

Ag@SnO2 nanosheets were prepared through a hydrothermal method followed by heat treatment and liquid reduction process. Many Ag nanoparticles (Ag NPs) dispersed uniformly over the surface of SnO2 nanosheets. The thickness was approximately 10 nm. After decoration with NPs, nanosheet sensors exhibited improved gas-sensing behaviors compared to pure sensor. response cross-linked decorated NP for ...
