Abstract:

The sodium alginate(SA) cation layer and the chitosan(CS) anion layer were modified by copper octocarboxyphthalocyanine[CuPc(COOH)8] and copper tetraaminophthalocyanine(CuTAPc) to prepare the CuPc(COOH)8-SA/CuTAPc-CS bipolar membranes(BPM). The ion exchange capacity and hydrogen ion transmigration rate of the CuPc(COOH)8-SA cation exchange membrane, and the ion exchange capacity and hydroxide ion transmigration rate of the CuTAPc-CS anion exchange membrane were increased. The water splitting rate at the interlayer of the CuPc(COOH)8-SA/CuTAPc-CS BPM was promoted. In comparison with the Fe-SA/mCS BPM modified by Fe3+, the membrane impedance, IR drop and swelling degree of the CuPc(COOH)8-SA/CuTAPc-CS BPM all obviously decreased. The IR drop of the CuPc(COOH)8-SA/CuTAPc-CS BPM was 0.9 V at a higher current density of 120 mA/cm2.
