Development of Artificial Leaf for Solar Hydrogen Production

Photosynthesis dye chlorophyll derivative chlorin-e6, viologen (electron carrier) and platinum nano-particle immobilized onto silica gel based thin layer substrate is for photoinduced hydrogen production is developed. When the chlorin-e6, viologen and platinum nano-particle immobilized onto substrate is irradiated with 100 mWcm-2 visible light in the presence of NADPH as an electron donor, the hydrogen production is observed. After 2 h irradiation, 6.0×10-8 mol of hydrogen is produced.
