Preparation and characterization of Copper based catalyst for different applications in catalysis via microwave irradiation. Microwave is used due to the significant dielectric heating system over convective heating where the reactant are added under mild reaction conditions. Metal oxides are mainly used in homogeneous catalysis and heterogeneous catalysis as well. Heterogeneous catalyst is better than homogeneous one as it is easy to separate components unlike homogeneous catalysis having problem in separating components
