Abstract：

How to promote water splitting at the intermediate layer and lower the IR drop of bipolar membrane (BPM) is the focus of BPM research. In the interlayer of bipolar membrane modified with nanometer–sized TiO2 as a photo-catalyst and Anthraquinone (abbreviated as Anth) as a photosensitizer. SEM and electrochemical workstation were used to characterize the BPMs. Experimental results showed that,the sandwich-type BPM exhibited a several good properties: a higher efficiency for the water splitting in the interlayer, a higher operation current density, lower impedance and working voltage. When the working current density is at 125 mA•cm-2, the working voltage is as low as 5.0 V under the UV illumination.
