Mechanochemical Treatment

The effect is studied of duration of mechanochemical impact, as well as modification sequence and grinding on the acidic and catalytic properties of synthesized catalysts based on natural zeolite in the conversion of n-octane.It is shown that the highest catalytic activity in the conversion of n-octane has a modified nickel-and zinc-based catalyst zeolite and structured bentonite clay, subjected to mechanochemical treatment for 12 hours after the promotion.

This paper discusses the influence of the synthesis technique on the porous structure, phase transformation, and catalytic properties of barium hexaferrite. Barium hexaferrite was synthesized by two different citrate gel methods. The first one involved metal salts, citric acid, and ammonia, while the second dispersed the same components in a polyacrylamide gel. X-ray diffraction analysis was used to determine the nature of the phase while the Brunauer, Emmett, and Teller (BET) analysis was used to study the porous structure of the material which were heat-treated at 700 °C, 900 °C, and 1200 °C. The catalytic activity of all materials in the combustion of methane was also measured.

Effect Of Structure

RuO2 has been used for various applications because of its good catalytic properties. To further improve its electrocatalytic properties, we used a nanocasting technique. By using this technique, we obtained structure-controlled (SC) RuO2 with a high surface area and an ordered porous structure, which created enhanced electrocatalytic properties over commercial RuO2 nanoparticles for both oxygen and chlorine evolution reactions.
