Electrochemical Stability of Few-Layered Phosphorene Flakes on Boron-Doped Diamond: A Wide Potential Range of Studies in Aqueous Solutions

Abstrakt

Two-dimensional phosphorene has attracted great interest since its discovery as a result of its extraordinary properties. Two-dimensional single crystals of phosphorene can be useful for electrochemical (EC) sensing applications due to their enhanced surface-to-volume ratio. We proposed to investigate the electrochemical performance of phosphorene deposited directly on boron-doped diamond (BDD) electrodes. Noncovalent interaction of phosphorene with BDD was achieved due to van der Waals interactions. This extends the potential range of EC studies in aqueous solutions due to the extraordinary wide range of the BDD potential window (−2 to 2.5 V vs Ag|AgCl|3M KCl). Cyclic voltammetry studies demonstrated irreversible electrochemical oxidation of the phosphorene, with peaks observed at different potentials depending on the sonication power during the liquid exfoliation of black phosphorus (BP). This indicated the formation of polyphosphoric quasi-oxide layers with undefined oxidation states of phosphorus. Electrochemical impedance spectroscopy showed the second time constant for high power sonicated BP, which was attributed to PxOy(OH)z formation. The subsequent film was responsible for limiting the charge transfer rate. The BDD enabled the EC behavior of phosphorene to be studied at high anodic potentials.
