Catalytic ozonation of 2-ethoxy ethyl acetate using mesoporous nickel oxalates

In this communication, synthesis of mesoporous nickel oxalate and its catalytic activity in ozonation of 2-ethoxy ethyl acetate (2-EEA) was reported. The mesoporous nickel oxalate was synthesized by simple method without using any template. The XRD and HR-TEM analyses indicated the formation of plate like nickel oxalate. The nitrogen adsorption-desorption analysis showed the mesopores over the catalyst surface with narrow pore size of 4.5 nm. About 0.125 g/L of dosage was found to be optimum for efficient removal of 2-EEA. The catalytic reusability studies demonstrated that nickel oxalate kept its catalytic activity in four consecutive cycles.
