摘要

The present study was undertaken to develop a novel and easy practical approach for synthesis of cyclopentanone, a versatile industrial ingredient. Accordingly, ceria-zirconia based nano-oxide catalysts, namely, Ce_xZr_(1-x)O2 and Ce_xZr_(1-x)O2/M (M = SiO2 and Al2O3) were prepared and evaluated for the title reaction. The physicochemical characterization has been achieved using different techniques, namely, XRD, BET surface area, XPS, Raman, OSC, and HREM. The catalytic results revealed that Ce_xZr_(1-x)O2 based nano-oxides are promising heterogeneous catalysts for synthesis of cyclopentanone. Amongst, the Ce_xZr_(1-x)O2/Al2O3 catalyst exhibited ～100% conversion with 75% desired cyclopentanone product selectivity owing to its favorable physicochemical characteristics.
