Efficient and Clean Photoreduction of CO2 to CO by Enzyme-Modified TiO2 Nanoparticles Using Visible Light

Year: 2010

Type: article

Abstract: A hybrid enzyme-nanoparticle system is described for achieving clean reduction of CO(2) to CO using visible light as the energy source. An aqueous dispersion of TiO(2) nanoparticles modified by attachment of carbon monoxide dehydrogenase (CODH) and a Ru photosensitizer produces CO at a rate of 250 mumol of CO (g of TiO(2))(-1) h(-1) when illuminated with visible light at pH 6 and 20 degrees C.
