Improvement of Synergetic Effect In Heterogeneous Catalysis By Addition Of Metal Oxides

Abstract

Over the past few years, synergetic effect has great importance in the heterogeneous catalysis structure. Synergetic effect provides the importance of the activity and stability of catalysis to produce desired product by improving the defects in the solid heterogeneous catalysis. These defects occur due to imperfection of the solid crystal lattices. And these defects can be improved by the addition of various metal oxides, which finally improve the synergetic effect or the defects in the heterogeneous catalysis. The metal oxide additives were found to influence the catalytic activity in the reaction, surface composition of the catalyst and the stability of catalysts during their operation. This paper reviews and assesses the effectiveness of different metal oxides additives in the heterogeneous catalysis activity and stability i.e. by improving synergetic effect in the heterogeneous catalysis.
