Aspects of Fe-Incorporation into CaTiO-SrTiO Perovskites and Their Catalytic Application for Ammonia SCO/SCR.

Perovskite materials in the CaTiO-SrTiO system doped with different amounts of iron (1, 2 and 5 mol.%) and various Ca/Sr ratios were prepared by the modified citrate method. Additionally, the materials with 0.

Solvothermal Synthesis of Medium-Entropy Oxide Spheres for Thermocatalytic Conversion of CO to Methanol.

New chemical compositions and structures for medium- and high-entropy oxides (HEOs) currently represent a promising new avenue in materials research for a wide range of applications including catalysis, energy storage, and ceramics. To speed up further development, synthesis methods for multicationic oxides are needed for controlling features like morphology, porosity, and chemical compositions. In this work, mesoporous spinel oxide spheres with five cations are synthesized using solvothermal synthesis techniques.

Some Aspects of Oxidation and Reduction Processes in Ti-Al and Ti-Al-Nb Systems.

The oxidation of titanium and titanium aluminides has attracted the attention of scientists for many years because of their high-temperature application. The most popular method to investigate oxidation behavior is the measurement of alloy mass changes during exposure to elevated-temperature under isothermal or thermal cycling conditions. However, the thermogravimetric method is not enough to establish an oxidation mechanism.

Catalysts Based on Strontium Titanate Doped with Ni/Co/Cu for Dry Reforming of Methane.

Two series of strontium titanates doped with Ni, Co, or Cu with general formula of SrTiMeO for Sr-stoichiometric and SrTiMeO for Sr-non-stoichiometric materials (where Me = Ni, Co or Cu and x were 0.02 and 0.06) were obtained by the wet chemical method.
