A semiconductor biohybrid system for photo-synergetic enhancement of biological hydrogen production.

CdS nanoparticles were introduced on E. coli cells to construct hydrogen generating biohybrid system via the biointerface of Tannic acid-Fe complex. This hybrid systems promoted good biological activity in high salinity environment. Under light illumination, as-synthesized biohybrid system has an 32.44% enhancement of hydrogen production in seawater through the synergistic effect.
