A nitrous-oxide decomposition catalyst comprises carrier material, and coating of rhodium, rhodium oxide, or palladium-rhodium alloy. An independent claim is also included for an apparatus for the decomposition of nitrous oxide formed in the Ostwald process, comprising the above catalyst(s) disposed ...
Ostwald’s process→Ostwaldov proces Ostwald’s process is a process by which the nitric acid can be obtained in three degrees. In the first stage ammonia and oxygen react (with platinum-rhodium as a catalyst), whereby the nitrogen monoxide and water emerge ...
This is initially understood through the industrially important process of methanol synthesis. Copper nanoparticles, one component of a methanol synthesis catalyst, are imaged under both Hydrogen and high vacuum conditions. This is the first ... Martin,T Edward 被引量: 0发表: 2015年 Composition and...
In fuel cells, the catalyst on the membrane must be very finely dispersed and must also provide a multitude of three-phase boundaries where the ion-conducting material and the electron-conducting material meet, and where the fuel is freely available. In batteries, the active mass can best be ...
Copper nanoparticle–based catalysts have been extensively applied in industry, but the nanoparticles tend to sinter into larger ones in the chemical atmospheres, which is detrimental to catalyst performance. In this work, we used dealuminated Beta zeolite to support copper nanoparticles (Cu/Beta-deAl...
A catalyst for the decomposition of NO under the conditions of the Ostwald process, comprising a carrier and a coating made of rhodium, rhodium/palladium or rhodium oxide applied thereto, ensures to yield NO with a particularly low content of laughing gas as the first process product....

Describe Ostwald's process for the manufacture of nitric acid. Give important uses of nitric acid. View Solution The catalyst used in the manufacture of nitric acid by Ostwald process is: View Solution Discuss briefly the principle involved in the manufacture of nitric acid by Ostwald's process...
Metal leaching poses a significant challenge for catalyst stability. However, if the reaction conditions are chosen appropriately, the here identified leaching process can be utilized to achieve particle growth by Ostwald ripening in a controlled manner. By changing the chemical nature of the metal ...
