The impact of surface Cu²⁺ of ZnO/(Cu_1-x Zn _x )O heterostructured nanowires on the adsorption and chemical transformation of carbonyl compounds.

ABSTRACT: The surface cation composition of nanoscale metal oxides critically determines the properties of various functional chemical processes including inhomogeneous catalysts and molecular sensors. Here we employ a gradual modulation of cation composition on a ZnO/(Cu_1-x Zn _x )O heterostructured nanowire surface to study the effect of surface cation composition (Cu/Zn) on the adsorption and chemical transformation behaviors of volatile carbonyl compounds (nonanal: biomarker). Controlling cation diffusion at the ZnO(core)/CuO(shell) nanowire interface allows us to continuously manipulate the surface Cu/Zn ratio of ZnO/(Cu_1-x Zn _x )O heterostructured nanowires, while keeping the nanowire morphology. We found that surface expos
