“…The sensitive material is based on palladiumfunctionalized carbon nanotubes (CNTs), a composite material that shows high affinity towards the identification of hydrogen isotopes. Based on previous research [10], we employed the same composite material (Pd-decorated MWCNT), developed via the reverse micelle synthesis route [11], to fabricate an electrochemical sensor, which can monitor the level of deuterium in heavy water. In this study, we focused on the electrochemical performance of the composite as the main characterization method.…”

In this study, we propose a palladium-functionalized CNT composite working as a sensitive material to evaluate the deuterium concentration in aqueous samples. The sensitive material was prepared by the deposition of Pd nanoparticles onto MWCNT–OH by the micellization process. A modified electrode was prepared by drop casting 60 μL of Pd-decorated MWCNT suspension on a clean glassy carbon electrode surface. The sensing behavior was investigated in a series of deuterium-enriched solutions ranging from 25 to 10.000 ppm. We performed cyclic voltammetry and impedance spectroscopy studies on the samples. The process is quasi-reversible with the reduction curve more pronounced than the oxidation curve, which indicates a low tendency to desorption for the hydrogen atoms.
