Self-assembled dendrite-like 3D-CeO2 nanostructures for non-enzymatic vitamin B2 sensor

[Display omitted] •CeO2 synthesized by hydrothermal reaction using sodium dodecyl benzene sulphate.•Dendritic CeO2 structure possess high electrocatalytic active and large surface.•3D CeO2/GCE modified electrode shows redox behavior in phosphate buffer (pH-7.0).•Modified electrode exhibits high sensitivity and nanomolar detection limits. Developing a one-pot route to construct hierarchical self-assembly of ordered nanostructures with promising functions is highly desirable, delivering enormous opportunities especially, in electrochemical sensing. Herein we present a highly efficient nanostructured dioxocerium (CeO2) for non-enzymatic electrochemical sensing of riboflavin. The CeO2 nanostructures possess homogeneity in sizes, unique morphologies, and remarkable structural stability. Furthermore, the resultant dendritic CeO2 nanostructures is deposited over glassy carbon electrode (GCE) surface (dendritic CeO2/GCE), and display well-defined redox peak with good sensitivity and excellent electrochemical reduction ability towards successive addition of riboflavin. Therefore, the proposed synthetic strategy provides a new methodology to explore various potentially active nanomaterials, and also modification of the electrode surface with these nanomaterials would offer a promising sensing device in various electrocatalytic applications.
