Photoenergy Conversion System Based on the Photosynthesis Dyes Conjugated Nanoparticle

The solar energy conversion system based on photosynthesis is promising as alternative energy invention technology of the future. In this review, the photoenergy conversion system based on the photosensitization of major photosynthesis dye pigment molecule, chlorophyll immobilized onto titanium dioxide or assembled into surfactant micellar system are introduced. One is the photoinduced hydrogen production system with the system containing an electron donor reagent, an electron carrier reagent, hydrogen producing catalyst and chlorophyll molecule assembled in surfactant micellar system. The other one is the photovoltaic conversion system based on the chlorophyll or chlorophyll derivative molecules immobilized onto nanocrystalline TiO2 film electrode.
