Reactive adsorption

WebThis improvement is linked to the increased porosity and the reactive adsorption of NO2 on copper, which leads to the formation of bidentate and monodentate nitrate. Even though less NO2 is adsorbed in moist conditions than in dry ones, the materials are more stable than in dry conditions and the NO retention is enhanced. WebReactive adsorption is a type of reactive separation process, where the chemical reaction is carried out in the fluid phase with the presence of an adsorbent and where one of the products is removed simultaneously to reconcentrate the reactants.
