One dimensional efficient photocatalyst based on plasmonic grating

We can summarize the benefits of water photocatalysis by two words: clean energy and purification pollutants, its problems as large gap electron–hole recombination. Scientists are still looking for a semiconductor whose lies in visible region, with pairs longer life time. One proposed solutions this field is combining available semiconductors (such TiO2) metal plasmonic properties. The existing will ensure that portion solar region involve action. It be absorbed metal, transformed into local leads to excitation processes semiconductor. Also, guarantee time electron-gap generated semiconductor, acts sink electrons In paper, we created unique photocatalyst based on one dimensional grating coated gold thin film covered TiO2 cap layer. By examining sample radiation, obtained rate sabotage 25 percent within three hours.
