  • 摘要: 电极的制备工艺及参数直接影响电极材料的活性。主要考察了C/PTFE质量比、碾压压力、煅烧温度、造孔剂NH4HCO3及稀土掺杂等因素对电极产出H2O2的影响规律。研究结果表明，电极最佳制备条件为：石墨和PTFE质量比为2：1、石墨、造孔剂和稀土元素质量比为6：1：1、碾压压力10 MPa、煅烧温度330℃。在pH=3、电解质Na2SO4浓度为0.05 mol/L条件下，电解2 h后，改性电极产生的H2O2从95 mg/L提高到350 mg/L，提高了268.4%。
    Abstract: Electrode preparation process and parameters directly influence the activity of electrode materials. This research mainly examines the C/PTFE mass ratio, rolling pressure, calcination temperature and NH4HCO3 and rare earth doped element such as pore-forming agent on the electrode produce the influence law of H2O2. Research results show that the best electrode preparation conditions are as follows: the quality of graphite and PTFE ratio of 2:1, graphite, pore-forming agent and rare earth elements quality ratio of 6:1:1, rolling pressure of 10 MPa, calcination temperature of 330℃. Under the conditions of pH=3 and [NaSO4]=0.05 mol/L, the H2O2 generated by 2 hours' electrolysis with modified electrodes increases by 268.4%, from 95 mg/L to 350 mg/L.
