The mechanism of photosynthesis, in which the sunlight is taken and turned into chemical fuel, was an inspiration for the scientists in their searching for alternative energies. Among other alternatives( wind energy, water power, etc), solar energy is one of the most reliable energy, the quantity of energy which the Earth is receiving in an hour, from the Sun, is greater than the amount which mankind consumes in one year.
Through photosynthesis process, the water and carbon dioxide is transformed into sugars,oxygen and hydrogen.Scientist tried to simulate the process and they have managed. The researches are aiming now the development of a substance to act as a catalysts, so that water to be converted into hydrogen. The technology intended to be used is photocatalytic overall water splitting, this one using nanoparticles activated by light. The important thing is that the technology mentioned is more efficient than the others and, above of all, less expensive.
By simulating the mechanism of photosynthesis, the final intended product would be not only the result of water splitting, but the obtaining of the liquid fuels, like methanol.
