CuO nanoparticles incorporated in hierarchical MFI zeolite as highly active electrocatalyst for non-enzymatic glucose sensing.

A hierarchical MFI zeolite, with typical micro/meso bimodal pore structures, was prepared by desilication method. CuO nanoparticles (NPs) were incorporated into the hierarchical MFI zeolite by impregnation method. CuO/hierarchical zeolite composites were characterized by X-ray diffraction, transmission electron microscopy and nitrogen sorption.

Direct electrodeposition of cable-like CuO@Cu nanowires array for non-enzymatic sensing.

Vertically aligned cable-like CuO@Cu nanowires array was synthesized using a template-directed electrodeposition strategy. The morphology, crystal structure, and surface property of nanowires array were investigated by SEM, HRTEM, XRD, and XPS, respectively. It is found that the free standing namowires are highly dense, and possess about 20 μm in length and 200 nm in diameter.
