摘　　要：目的研究不同催化剂制作工艺对水电解产生臭氧的电流效率的影响。方法采用SPE固体聚合物水电解器做臭氧发生器,以二氧化铅为阳极,碳载铂为阴极,考察不同催化剂下水电解制备臭氧的电流效率。结果以PbO2为原材料,均匀混合2 wt%的PTFE所制得的阳极材料,在表观电流密度1.6 A·cm-2下工作,长时间工作的平均电流效率都在30%以上。结论臭氧作为一种强氧化剂,可以用较低的能耗在深度处理载人航天器冷凝水上发挥作用。Objective To study the impact of different fabrication processes of anode catalyzers on the current efficiency of SPE water electrolyze ozone generator. Methods SPE water electrolyzer was used as the ozone generator and lead dioxide served as the anode material,Pt /C as cathode material. The electrolysis performance with various catalyzers were tested. Results Using lead dioxide material with 2wt% of PTFE as anode,the average long-period current efficiency of the generator exceeded 30%. Conclusion As a kind of powerful oxidant,ozone can be used in advanced treatment of humidity condensate in manned spacecraft with low energy consumption.
