Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 18742-02-4, Name is 2-(2-Bromoethyl)-1,3-dioxolane, SMILES is C(C1OCCO1)CBr, belongs to copper-catalyst compound. In a document, author is Liu, Tangkang, introduce the new discover, Computed Properties of C5H9BrO2.
La promoted CuO-MnOx catalysts for optimizing SCR performance of NO with CO
La-Cu-Mn-O catalysts with different La contents were prepared and evaluated for low-temperature selective catalytic reduction of NO by CO (CO-SCR) to study the structure-activity relationship. The results demonstrated that lanthanum was conducive to the decrease in the size of copper and manganese and preventing their agglomeration, enabling the enhancement in reducibility of the catalysts, which promotes the increase in exposed active sites and the reactivity between reactants (NO and CO). Furthermore, La3+ gains advantages from enhancing the redox couples of Mn4++Cu+<-> Mn3++Cu2+, leading to the formation of high-proportioned active ions (Cu2+ and Mn3+) and surface oxygen defects in abundance, which favors the generation of numerous Cux+-square-La3+-square-Mny+ species (x = 2 or 1 and y = 3 or 4, square represents a surface synergetic oxygen vacancies). The abundant synergistic nodes promote the dissociation of NO and the transfer of dissociated oxygen, making the conversion of NO reach 100% at about 250 degrees C to reduce the active temperature. According to the in-situ DRIFTS results, we proposed a reasonable reaction mechanism for further understanding the routes in the NO + CO model reaction.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 18742-02-4 is helpful to your research. Computed Properties of C5H9BrO2.
