제목 Extrinsic Pseudocapacitive Features of Molecular-Level Controlled 2D Oxidized Black Phosphorus
초록 Bulk and two-dimensional black phosphorus (BPs) are considered as the candidates for energy storage materials, but their performance are suffered by the low rate and cycling capabilities due to intrinsic (de-)alloying mechanism. In this work, we demonstrate the reversible extrinsic pseudocapacitive features on 2D oxidized BP (oBP) that are strongly hybridized with graphene. oBP-based electrodes show capacitance of 478 F g–1 with rate capability of 72% and retention of 91% over 50,000 cycles. The surface redox reaction at oxidized P sites was investigated by In-situ spectroelectrochemical and theoretical calculations.
