Electrocatalysts consisting of polypyrrole (PPY) and Co deposited on carbon black (CB) at several compositions were prepared and tested for the oxygen reduction reaction (ORR) in a HClO4 buffer (pH = 1) using a rotating ring-disk electrode (RRDE). It
Characterization and activity of vanadia-promoted Pt/ZrO2 catalysts for the water–gas shift reaction

Catalysis Today. 138:235-238
Pt/ZrO 2 catalysts for the water–gas shift (WGS) were promoted with various amounts of vanadia. Analyses by XRD, N 2 adsorption, Raman, and UV–vis DRS showed that vanadia is present below monolayer coverage as monovanadate and polyvanadate, with

Sodium montmorillonite was intercalated with the Keggin ion (hydroxyaluminum polycation) and calcined at 400 °C. Then, doping with Fe 3 + , Cu 2 + , or Zn 2 + was carried out. On the obtained samples, HAS breakthrough capacity tests were carried out

Sodium-rich montmorillonite was modified with iron in order to introduce active centers for hydrogen sulfide adsorption. In the first modification, interlayer sodium cations were exchanged with iron. In another modification, iron oxocations were intr
