Semiconductor-metal nanoparticle hybrids with natural and artificial proton pump for hydrogen production
Abstract
Aspects of the disclosure relate to an efficient entirely man-made nanobio hybrid fabricated through cell-free expression of transmembrane proton pump followed by assembly of the synthetic protein architecture with semiconductor nanoparticles for photocatalytic H2 evolution. The system produces H2 at a turnover rate of 240 μmol of H2 (μmol protein)−1 h−1 under green and 17.74 mmol of H2 (μmol protein)−1 h−1 under white light at ambient conditions, in water at neutral pH with methanol as a sacrificial electron donor. Robsutness and flexibility of this approach allows for systemic manipulation at nanoparticle-bio interface toward directed evolution of energy materials and devices.
