| Abstract: |
| Hydrogen is a proper chemical storage for solar energy, and considered a green and pollution free energy. The feasibility of solar-driven hydrogen generation from water cleavage is investigated using commercial TiO2 nanoparticles, and life cycle assessment (LCA) of the process is estimated. TiO2 is fully characterized. The results confirm the efficacy of TiO2 for solar-driven photocatalytic water splitting with the same production rate of H2. The maximum calculated photocatalytic rate of hydrogen over PC was 4.76 µmole/h under sunlight. As well the rate of produced H2 is dependent PC dose. There is highly fitted for relation between Kapp with PC dose with r2 of 0.96. It is obvious that kapp is highly dependent concentration of TiO2. The outcome emphasized of the practicability for application of solar system for renewable energy with cost-effective technology. Also, LCA study of solar-driven H2 production is showed that higher carbon dioxide and as well as global warming potential originated from operation of system. |
