Abstract:
Recently, tuning catalytic material has gained huge importance for enhancing the catalytic performance of reactions. The present work describes the influence of aluminum in copper-manganese composite oxide with respect to the NO-CO redox reaction. The Al3+ fabricated composite oxide showed the highest conversion in a lower temperature window. The nanocomposite metal oxide of Cu-Mn formed as a porous structure with aluminum and helped in establishing a more surface acidic/basic character on the catalyst. These acidic/basic sites are crucial in activating the NO and CO chemisorption for significant redox conversion.

Schottky Barriers
Schottky barriers arise when a metal with a work function (Φm) contacts a semiconductor with a different work function (Φs). Initially, electrons transfer until the Fermi levels of the metal and semiconductor align at equilibrium. For instance, if Φm > Φs, the semiconductor Fermi level is higher than the metal's before contact. The...
