Low-Temperature Decomposition of Nitrous Oxide on Cs/MexCo3−xO4 (Me: Ni or Mg, x = 0–0.9) Oxides

چکیده
Mixed oxides MexCo3−xO4 (Me: Ni or Mg, x = 0–0.9) with a spinel structure were synthesized by precipitation from Me, Co nitrate solutions using (NH4)2CO3 as the precipitating agent subsequent modification of dry precipitate cesium Pechini method and calcination. The samples studied XRD, TPR, TPD methods. Their catalytic activity was in low-temperature (150–350 °C) nitrous oxide decomposition process. It shown that an increase degree substitution cobalt (x) leads to significant decrease crystallization oxides, specific surface area, formation weakly bound oxygen species. highest catalysts 0.1, especially nickel-substituted sample, which contained maximum amount difference influence Mg on properties is discussed.

The kinetics of N2O decomposition to gaseous nitrogen and oxygen over HZSM-5 catalysts with low content of iron (<400 ppm) under transient and steady-state conditions was investigated in the temperature range of 250–380 8C. The catalysts were prepared from the HZSM-5 with Fe in the framework upon steaming at 550 8C followed by thermal activation in He at 1050 8C. The N2O decomposition began at ...

High temperature cyclic voltammetry on microsamples was used for the investigation of the electrochemical stability of BIMEVOX.10 materials. The electrochemical measurements were performed on a three-electrode cell of the type: PtumicrosampleuYSZuPt with the interface PtuYSZ as a pseudo reference electrode. The experiments were performed in nitrogen containing a small quantity of oxygen. The ce...

Massive superconducting MgB(2) nanofibers are obtained for the first time from Mg(BH(4))(2). The technique optimizes reaction conditions to only 1 h at 460 °C and provides nanofibers which exhibited satisfying superconducting properties. The morphology transformation according to temperature changes and the special mechanism of precursor inductive synthesis are discussed.
متن کاملP110: Nitrous Oxide and Neuroinflammation
Nitrous oxide was an anaesthetic gas that was used for many years. There were many anaesthetic drugs in operations with many side effects. Nitrous oxide had some side effects too. But it was a safe gas in many times. In hospital personnel who worked in operating rooms exposure to this gas was important. The objective of this study was the introduction of nitrous oxide and neurologic side ...
