【摘要】 利用氯化胆碱和乙二醇（物质的量比1∶2）形成的低共熔溶剂做溶剂，加入Fe（NO₃）₃,利用离子热法制备乙二醇铁，并对其进行SEM、EDX、XRD、IR表征，发现为结晶度高的3D球形纳米颗粒。将该催化剂用于催化1.0 mol/L KOH+0.5 mol/L尿素溶液的电解氧化反应。由极化曲线得，当电流密度为10 mA·cm^-2时，电压为1.37 V,Tafel斜率为45 mV·dec^-1。基于乙二醇的低共熔溶剂既做反应介质又做反应物，可以减少反应物组分，减少浪费，减少碳排放。更多还原

【Abstract】 Using the deep eutectic solvent formed by choline chloride and ethylene glycol（molar ratio 1∶2） as solvent, ethylene glycol iron was prepared by ionothermal method.SEM,EDX,XRD,IR characterizations were explored.It was found to be 3 D spherical nanoparticles with high crystallinity.The catalyst was used to catalyze the electrolytic oxidation reaction of 1.0 mol/L KOH + 0.5 mol/L urea solution.The voltage was required 1.37 V to achieve the current density of 10 mA·cm^-2,while the Tafel slope was 45 mV·dec^-1.Based-ethylene glycol deep eutectic solvent is used as both the reaction medium and the reactant, which can reduce the components of the reactant and reduce carbon emissions.更多还原
