摘要
在温和条件(常温、常压、近中性)下原位电解制备WO3/Ni-Bi析氧催化剂,该催化剂具有较好的析氧催化性能(析氧速率为4.50μmol/h,电流密度为1 mA/cm2时析氧过电位为258 mV)。通过电化学方法对其析氧性能和稳定性能进行测试,并通过XRD、SEM、EDS、XPS表征方法对其形貌、结构及组成进行分析。
A WO3/Ni-Bi oxygen-evolution catalyst was generated in situ electrolysis under mild condition ( ambient temperature, pressure and nearly neutral), which showed excellent catalytic activity with the oxygen-evolution rate of 4.50 μmol/h, the overpotential of 258 mV at the current density of 1 mA/cm2. The oxygen-evolution performance and stability were tested by electrochemical means. The structure, morphology, and composition of the catalyst were investigated by XRD, SEM, EDS and XPS.
