The Group of scientists from Tokyo Institute of Technology (Tokyo Institute of Technology), under the leadership of Professor Osamu Ishitani (Osamu Ishitani) managed to find a practical way of applying the effect of artificial photosynthesis to transform carbon dioxide (CO2 ) in the carbon monoxide (CO). To do so, as fotokatalizatora researchers used sophisticated supermolekulyarnoe integrated renievoe-ruthenium (Ru-Re) connection. Carbon, or in another greenhouse gas - a side effect of our civilization, in recent times is present in the atmosphere of the planet that is called a surplus, and with these izbytkami no longer cope or oceans, partly it is absorbed, either terrestrial flora that feed on carbon dioxide and oxygen to replace Generation through photosynthesis. Recall that carbon dioxide CO2 is a fairly stable connection. Another case of carbon monoxide (CO, carbon monoxide, or simply carbon monoxide), which is being acquired as a result of the industrial scale of artificial photosynthesis, would help not only to efficiently dispose of surplus greenhouse gas in the atmosphere, but also in the future would at minimum cost to produce very useful hydrocarbons such as starch or saccharose virtually out of thin air. The original object of study group of Japanese scientists - complex compounds based on rhenium (Re), a remarkable fotokatalizatorom used for the decomposition of water into hydrogen and oxygen, and the decomposition of carbon dioxide and carbon monoxide with a quantum efficiency of 0. 59. The problem is that renievoe complexes rather reluctant to absorb the energy spectrum of sunlight the most effective visible range 400-800 nm, preferring the ultraviolet part of the wavelength of less than 450 nanometers, and the connection is quite unstable. The scientists focused on the study of complex compounds based on ruthenium (Ru), known as an excellent sensibilizator and absorbing visible light spectrum of 500 nm and above with high quantum efficiency of 0. 21. The resulting Re-Ru supermolekulyarnoe complex compounds in the presence of reducing class amines able to photosynthesis, with a very high quantum efficiency. now on the agenda of researchers - from supermolekuly greater stability, as well as the optimization of the length of ligands in untied system and structure renievogo complex. In other words, to the factories of artificial photosynthesis is far, but the prospects are encouraging.
