Enhanced 1,2-dichloroethane removal using g-CN/Blue TiO nanotube array photoanode in microbial photoelectrochemical cells.

The compound 1,2-dichloroethane (1,2-DCA), a persistent and ubiquitous pollutant, is often found in groundwater and can strongly affect the ecological environment. However, the extreme bio-impedance of C-Cl bonds means that a high energy input is needed to drive biological dechlorination. Biotechnology techniques based on microbial photoelectrochemical cell (MPEC) could potentially convert solar energy into electricity and significantly reduce the external energy inputs currently needed to treat 1,2-DCA.

External potential regulated biocathode for enhanced removal of gaseous chlorobenzene in bioelectrchemical system.

Microbial electrolysis cell (MEC) with a biocathode could provide extra reaction driving force for gaseous chlorobenzene (CB) removal. In this work, external potentials (-0.1 to -0.

[Removal of Nitrate Nitrogen by Microbial Photoelectrochemical Cell: PANI/TiO-NTs as a Photoanode].

The use of microbial photoelectrochemical cells (MPECs) for the removal of contaminants is a cost-effective and environment-friendly method. Based on the preparation of polyaniline/titanium dioxide nanotube array (PANI/TiO-NTs) composite photoelectrodes, an MPEC system comprising PANI/TiO-NTs photoanode and biocathode was constructed and the removal performance of nitrate nitrogen (NO-N) was studied. The experimental results showed that the PANI/TiO-NT electrode exhibited the best photoelectric performance when the PANI loading time was 80 s.
