| 摘要 |
The invention is directed to a system for hydrogen production from water, known as a photoelectrochemical system. The system integrates a semiconductor material and a water electrolyzing material inside a monolithic design, to produce hydrogen directly from water. Natural or synthetic light is used as the main or sole source of energy. The water electrolyzing material is melanins, melanin precursors or melanin derivatives, melanin variants, melanin analogues, natural or synthetic, pure or mixed with organic or inorganic compounds, metals, ions, drugs. The system or light absorbing compound generates enough energy to start, lead and complete the photoelectrolysis reaction. The system can generate hydrogen, oxygen and high energy electrons, and can synthesize water from the union of hydrogen and oxygen, thereby generating electricity. The system can also be coupled to other processes, generating a multiplication effect, and can be used for the reduction of carbon dioxide, nitrates, sulphates and the like.
