[Display omitted] •A facile palladium functionalized reduced graphene oxide paper was prepared via one-pot co-reduction method.•Evenly-distributed Pd particles show to decorate graphene paper surface and interpose between graphene sheets.•As-prepared freestanding Pd/rGOP can potentially be used as a glucose sensor. A free-standing palladium/reduced graphene oxide paper (Pd/rGOP) based on one-pot co-reduction was prepared. The as-prepared Pd/rGOPs contain evenly distributed Pd particles interposing between the rGOP layers. The structure and composition of Pd/rGOP were characterized by SEM, EDX, XRD and Raman spectra. We investigated the glucose sensing performance of Pd/rGOP by chronoamperometry, the sensitivity reach as high as 6.70 µA mM−1 cm−2 with the linear range between 0.5 mM and 8 mM. The sensor also exhibits a good anti-interference ability and detection selectivity toward the interference. The proposed sensor has great potential to become a reliable tool in point-of-care medical devices.
