Effect of Cu Insertion into SnO₂ Framework on Surface Properties and Carbonyl Sulfide Adsorption Performances.

The objective of this study is to introduce Cu into SnO₂ sorbent for improving its COS adsorption capacity. Cu-doped SnO₂ adsorbents were synthesized using a conventional sol-gel method with citric acid. X-ray diffraction studies revealed that up to 0.

Ni Substitution Effect on the Fe Position of Spinel Fe2MnO4 Particles for Chemical Looping Combustion.

The purpose of this study was to use a spinel structure to improve the performance and stability of chemical looping combustion processes. The oxygen carrier employed was Fe2MnO4, in which Ni was substituted at the Fe sites. Fe2-xNixMnO4 spinel particles were successfully synthesized by a sol-gel method.

Photoreduction of Carbon Dioxide to Methane Over SbSn TiO with High Conductivity.

In order to enhance the photoreduction of CO2 to CH4, a new type of photocatalyst, Sb1.5Sn8.5-xTixO19.

Surface modification of layered perovskite SrTiO for improved CO photoreduction with HO to CH.

Layered perovskite SrTiO photocatalyst was synthesized by using sol-gel method with citric acid. In order to increase the surface area of layered perovskite SrTiO, and thus to improve its photocatalytic activity for CO reduction, its surface was modified via hydrogen treatment or exfoliation. The physical and chemical properties of the prepared catalysts were characterized by X-ray diffraction, high-resolution transmission electron microscopy, elemental mapping analysis, energy-dispersive X-ray spectroscopy, N adsorption-desorption, UV-Vis spectroscopy, X-ray photoelectron spectroscopy, photoluminescence, and electrophoretic light scattering.

Enhancement of hydrogen production from MeOH/H2O photo-splitting using micro-/nano-structured SrSnO3/TiO2 composite catalysts.

Micro-/nano-structured SrSnO3/x wt.-% TiO2 composites (x = 10, 20, and 30) were designed using a mixed method, a typical hydrothermal and impregnation method, to enhance hydrogen production from MeOH/H2O photo-splitting. All the materials obtained exhibited a perovskite structure.
