Flexible vanadium-doped Ni2P nanosheet arrays grown on carbon cloth for an efficient hydrogen evolution reaction

The paper published on February 19, 2019, is my work during my Ph.D. The work was carried out under the careful supervision of researcher Yue Li and Xin Yang Li, and with the support of researcher Wei Tong at the Center for Steady State Strong Magnetic Fields.The catalyst preparation for this work was performed by hydrothermal method combined with low-temperature phosphorylation on carbon cloth to prepare V-doped Ni2P nanosheet array catalysts (V-Ni2P NSAs/CC), and electrocatalytic measurements were performed at room temperature using a standard three-electrode system at the Tatsuwa electrochemical workstation, with graphite rod electrodes and Ag/AgCl being used as counter and reference electrodes. All potentials were converted to reversible hydrogen electrode (RHE) scale using ERHE = E + EAg/AgCl + 0.0591 x pH. The electrolyte solution was purged with N2 for approximately 30 minutes prior to measurement to ensure oxygen saturation and to maintain oxygen flow during the measurement. Polarization curves were p
