Preparation of Sandwich Bipolar Membrane and Its Photocatalytic Properties
Abstract:
The mCMC/TiO2-Oxine/mCS bipolar membrane(BPM) was prepared by using carboxymethyl cellulose(CMC) as the anodic layer,chitosan(CS) as the cathodic layer,and Cr3+ and glutaraldehyde as the linking reagents. Nano-TiO2 was taken as an interlayer. The BPM showed a sandwich composition. TiO2 was modified with the photosensitizer,oxine as a photocatalyst to enhance the photocatalytic properties for splitting the water in the interlayer of the BPM. The bipolar membrane exhibited an excellent hydrophilic performance,lower impedance and working voltage. When the working current density was as high as 0.12 A/cm2,the working voltage was as low as 5.0 V with UV irradiation.
