铬掺杂诱导打破CoFe层状双氢氧化物中的比例关系以改善氧析出

The paper was published on July 15, 2019, and is my work during my PhD. The work was carried out under the careful supervision of researcher Yue Li and with the support of Professor Weichao Wang from Nankai University and Xilin Zhang from Henan Normal University.The catalyst synthesis in this work was mainly performed by hydrothermal method, and electrocatalytic measurements were performed at room temperature using a standard three-electrode system at the C.H. 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 O2 for approximately 30 minutes prior to measurement to ensure oxygen saturation and to maintain oxygen flow during the measurement. Polarization curves were performed with LSV at a scan rate of 2 mV s-1.
