摘　　要：以壳聚糖、羧甲基纤维素钠、聚乙烯醇作为阴离子交换膜和阳离子交换膜的基本材料,纳米TiO_2-Sn O_2复合光催化剂作为双极膜的中间层,制备m CMC/TiO_2-Sn O_2/m CS双极膜。在紫外光照射下,该双极膜水解离能力高,亲水性能好,交流阻抗低。另外,其工作电压低,电流密度为90 m A/cm^2时,电解槽工作电压小于5.5 V。The m CMC/TiO_2- Sn O_2/m CS bipolar membrane was prepared by chitosan, sodium carboxymethyl cellulose and polyvinyl alcohol solution as basic materials of anion exchange membrane and cation exchange membrane,nano- TiO_2- Sn O_2 as an interlayer. The bipolar membrane exhibited excellent water splitting ability and hydrophilic performance,lower impedance. Then the working voltage was as low as 5. 5 V when the working current density was as high as 90 m A/cm2 with UV irradiation.
