Researchers have constructed a molecular catalyzer that can oxidize water to oxygen very rapidly. In fact, these scientists have managed to reach speeds approximating those of natural photosynthesis. The speed with which natural photosynthesis occurs is about 100 to 400 turnovers per seconds. Scientists have now reached over 300 turnovers per seconds with their artificial photosynthesis. The research findings play a critical role for the future use of solar energy and other renewable energy sources.
