World’s most efficient artificial photosynthesis system to make power plants cleaner


With threats of carbon dioxide induced global warming looming large, researchers from over the globe have come together to develop futuristic systems that can regulate the amount of carbon dioxide currently being emitted. To help incinerators and power plants reduce carbon emissions, Panasonic has come up with a new artificial photosynthesis system that can convert carbon dioxide into clean organic materials, with record efficiency.

The system splits water into its atomic components that is hydrogen and oxygen, and then uses the produced hydrogen to convert harmful carbon dioxide into formic acid – a relatively harmless product in relation to global warming. The technology makes use of a nitride semiconductor inside a water container, where acting as a photo-electrode, nitride splits water into oxygen and hydrogen. With the use of a catalyst, electrons are excited to the required levels of energy to reduce carbon dioxide to form formic acid.

The system is much simpler in design when compared with other similar systems being developed in other parts of the world. Moreover, Panasonic’s all-inorganic artificial photosynthesis system carries on the process at a record efficiency of 0.2 percent.
