Synthesis, characterization and catalytic activity of Ce1Mg xZr1-xO2 (CMZO) solid heterogeneous catalyst for the synthesis of 5-arylidine barbituric acid derivatives

Abstract

A series of Ce1MgxZr1-xo2 (CMZO) mixed metal oxide with different molar ratio were prepared by simple co-precipitation method. The prepared materials were tested for their catalytic activity performance using Knoevenagel condensation of various aromatic aldehydes with barbituric acid under solvent-free condition in microwave. The best catalytic activity was obtained with CMZO (1:0.6:0.4). The synthesized materials were characterized by using XRD, FT-IR, SEM-EDS techniques.
