Solar-driven Photocatalyzed Hydrogen Production from Water cleavage: Evaluation and Process Life Cycle Assessment

Abstract

Hydrogen is proper chemical storage for solar energy and is considered a green and non-pollution energy. The feasibility of solar-driven hydrogen generation from water cleavage is investigated using commercial TiO2 nanoparticles, and the process of life cycle assessment (LCA) 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 a signification corelation between Kapp with PC dose with r2 of 0.96. Reaction rate constant for hydrogen production is significantly dependent concentration of TiO2. The outcome emphasized the practical application of solar-driven, cost-effective technology for production renewable energy. Also, LCA study of solar-driven H2 production is showed that higher carbon dioxide and as well as global warming potential with lower climatic change impact originated from operation of system.
