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。 The WO3 / Ni-Bi oxygen evolution catalyst was prepared by in-situ electrolysis under mild conditions (room temperature, atmospheric pressure and near neutrality). The catalyst has good oxygen evolution catalytic performance (oxygen evolution rate of 4.50μmol / h, current density Oxygen evolution overvoltage of 258 mV at 1 mA / cm2). The performance of oxygen evolution and stability was tested by electrochemical method. The morphology, structure and composition of the samples were analyzed by XRD, SEM, EDS and XPS.
