Synthesis and Investigation of the Catalytic Activity of Nanostructured Potassium Titanates Doped by Ni, Mg, Al, Fe, and Cr

Resumo

This work presents the results of investigating the catalytic activity of potassium titanate nanomaterials doped by different metals (Ni, Mg, Al, Fe, and Cr) in oxidation reactions of hydrogen and carbon monoxide. It is shown that the best characteristics of the oxidation of the investigated gases have nanotubes doped by aluminium (0.3 × 10^–5 mol H₂/(g s) at 250°C and 10^–5mol CO/(g s) at 350°C).
