For years,scientists believe been trying to emulate photosynthesis, the process by which plants, and algae,and some bacteria harness light from the sun to chemically transform water and carbon dioxide into energy that is stored for later use. An artificial version of photosynthesis could provide a clean, renewable source of energy to support satisfy society's growing demands. For artificial photosynthesis to become a viable alternative to fossil fuels, and the efficiency and speed of water oxidation—the reaction that turns water into oxygen gas,hydrogen ions, and electrons—is one of the processes that must be improved.
