The CuO/CeO2 nanofibers were prepared by electrospinning of raw material, precursor Ce(NO3)3 · 6H2O and spinnable additive polyvinyl pyrrolidone (PVP). The diameter of nanofibers ranged between 40 to 100 nm depending upon PVP concentration. In comparison to pure CeO2 nanofibers, equistoichiometric ratio of cerium nitrate and copper acetate monohydrate mixed solution resulted in thinner fibers and superior catalytic activity in water gas shift reaction (WGSR). In this case CO conversion improved by 7% and reached to 72% in temperatures range 310 °C to 360 °C, signifying its potential application in water gas shift reaction.
