| Abstract |
A microbial electrolysis cell (MEC) is novel technology for hydrogen production from organic matters such as wastewater using bacteria for the future. Pure hydrogen production in the MEC is one main challenge for practical application. However, the methane production by methanogens through hydrogen consumption has been a main drawback. In order to solve this problem, we have performed research in which visible light acts as methanogen inhibitory factor at the cathode where hydrogen is produced. For this purpose, p-type semiconductors such as polyaniline nanofiber and metal oxide have been used as photocathodes as visible light harvesters. Results show that much hydrogen was successfully produced in the MEC with 0.8 V external bias with minimal amount of methane. These results demonstrate the possibility of using p-type semiconductors for utilizing visible light for an effective production of hydrogen while suppressing methanogenesis. |
