Advancing Biotechnologies for Fuel Generation: Exploiting Transmembrane Cytochromes for Solar Energy Conversion
Lead Research Organisation:
University of Leeds
Department Name: Astbury Centre
Abstract
Solar energy is our most abundant energy source and has enormous potential as a clean and economical energy supply. We wish to tap into this under-utilised source of power and address the direct conversion of solar energy to a renewable fuel; a major technological challenge of our time. This PhD project will use Synthetic Biology principles to mimic the principles of plant photosynthesis. Hybrid systems will be designed and build in which light-harvesting nanoparticles (e.g., TiO2 or quantum dots) are coupled to redox-active proteins and enzymes, combining the catalytic specificity of enzymes with the photo-stability and light-harvesting capabilities of semi-conducting nanoparticles for fuel production.

Towards compartmentalized photocatalysis: multihaem proteins as transmembrane molecular electron conduits.
in Faraday discussions
| Description | The research has demonstrated a proof-of-concept that a conductive membrane protein can be coupled to inorganic light harvesting nano-particles, and thus use light energy to drive chemical reactions within a nano-compartment. Several ways of have been attempted on introducing hydrogen evolving catalysts within these proof-of-concept nano-compartments and work has been carried out aiming to map interaction of a conductive protein (MtrC) and titanium dioxide nanoparticles. |
| Exploitation Route | The findings explore some ways to combine different materials (inorganic, organic and biological) into nano-compartments for converting solar energy to chemical energy. Further research is required to incorporate fuel producing catalyst. In addition, further characterization of the benefits and drawbacks of the energy transfer across the membrane should be made and compared with other nano-structured systems in order to increase the efficiency of solar to fuel energy conversion. The findings also relate to use of light energy to power an encapsulated reaction, which could potentially be further developed for chemical synthesis within chemical nano-reactors. |
