原始语种摘要: Abstract(#br)A hybrid structure composed of a 3D network of graphene oxide hydrogels (GOHs) and Co 3 O 4 nanoflowers (NFs) was fabricated by using a one pot hydrothermal process. Scanning electron microscopy and transmission electron microscopy revealed the formation of Co 3 O 4 NFs in the GOH networks, which resulted in an increase in the surface area and in electrocatalytic activity. Cyclic voltammetry (CV) was used to evaluate the glucose sensing ability of the various samples fabricated in this study. The Co 3 O 4 NF/GOH sample exhibited glucose sensitivity as high as 492.8μAmM −1 cm −2 , which is 20 times that of pure GOH. This sample also exhibited excellent glucose sensing in real blood samples (horse and rabbit serums) as...
