Enhanced H2and reduced CO level by use of electrospun CuO/CeO2nanofibers catalyst for water gas shift reaction

Abstract

The CuO/CeO2nanofibers 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 CeO2nanofibers, 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. © 2016 American Scientific Publishers.
