A mSA-mCS bipolar membrane was prepared by sodium alginate/polyvinyl alcohol (SA/PVA) and chitosan/polyvinyl alcohol (CS/PVA) modified by Fe 3? and glutaraldehyde as linking reagents, respectively. The mSAmCS bipolar membrane was investigated by FT-IR, SEM, I-V curves, ion exchange capacity and changes of pH in the anode and cathode chambers. The SA-CS/PVA bipolar membrane was used as a separator in the electrolysis cell to electrogenerate 3-methyl-2-formylaminopyridine. The product yield was 49.8% and higher than that produced in a Nafion mono-membrane-equipped cell. Compared with the traditional chemistry method, the electro-generating process is moderate and eliminates pollution to the environment.

“…The pH of electrolyte can be maintained by using bipolar membrane to keep metal ions soluble. For H þ and OH À , generated by the splitting of the water when the current reaches a critical value, migrate to the anode and cathode, respectively [205,212]. Ter Heijne et al proved that the MFC with a bipolar membrane combined with ferric iron reduction on a graphite cathode was shown to have a high Coulombic efficiency and energy recovery, for the low pH of the catholyte was required to keep ferric iron soluble [26].…”

“…In an electric field, water at the interlayer of a BPM can be split into hydroxide ions and protons by a disproportionation reaction [4][5][6]. In general, a good membrane is one with low energy consumption, high current efficiency, high product purity, and good long-term stability [7].…”

A cystine-modified TiO 2 visible-light photocatalyst was prepared by the sol-gel method and characterized by X-ray diffraction (XRD), ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS), and X-ray photoelectron spectroscopy (XPS). The XRD results showed the cystine-modified TiO 2 was in the anatase phase, but with reduced size. UV-Vis DRS indicated that cystine-modification could reduce the band gap of TiO 2 and enhance the absorption of visible light. The XPS spectra showed that the cystine-modified TiO 2 sample contained C, N, and S, and that some of the C, N, and S entered the TiO 2 lattice. The cystinemodified TiO 2 visible-light photocatalyst was added to a chitosan (CS) anionexchange layer to prepare PVA-CMC/modified TiO 2 -PVA-CS bipolar membrane (BPM; here, PVA denotes poly(vinyl alcohol), CMC denotes carboxymethylcellulose, and the solidus ''/'' denotes the interlayer) by a paste method. The membrane was characterized by determination of contact angle, J-V characteristics, and AC impedance spectroscopy, among other techniques. Experimental results showed that the cystine-modified TiO 2 visible-light photocatalyst was a better photocatalyst than TiO 2 for splitting of water at the interlayer of the BPM. The membrane impedance and trans-membrane voltage drop (IR drop) of the modified BPM clearly decreased under sunlight irradiation. At a current density of 60 mA/cm 2 , the cell voltage of the PVA-CMC/modified TiO 2 -PVA-CS BPM decreased by 0.9 V. Moreover, the hydrophilicity of the modified BPM was increased and its mechanical properties were improved.
