Pt-grown carbon nanofibers for detection of hydrogen peroxide.

ABSTRACT: Removal of left-over catalyst particles from carbon nanomaterials is a significant scientific and technological problem. Here, we present the physical and electrochemical study of application-specific carbon nanofibers grown from Pt-catalyst layers. The use of Pt catalyst removes the requirement for any cleaning procedure as the remaining catalyst particles have a specific role in the end-application. Despite the relatively small amount of Pt in the samples (7.0 ± 0.2%), they show electrochemical features closely resembling those of polycrystalline Pt. In O₂-containing environment, the material shows two separate linear ranges for hydrogen peroxide reduction: 1-100 μM and 100-1000 μM with sensitivities of 0.432 μA μM^-1 cm^-2 and 0.257 μA μM^-1 cm
