KAIST develops a molecular platform for the selective control of oxygen reaction pathways
KAIST researchers have developed a new molecular platform using germanium to selectively control oxygen reaction pathways. This innovation offers a cost-effective alternative to precious metal catalysts for energy-conversion technologies like batteries and fuel cells.
Why it matters
It provides a fundamental design principle for more efficient and affordable catalysts, potentially accelerating the development of sustainable energy technologies.
Controlling how oxygen reacts is important for improving technologies such as batteries, fuel cells , and environmentally sustainable chemical processes. A KAIST research team has developed a new molecular system that can selectively switch the pathway through which electrons are transferred during oxygen activation. The findings are expected to provide a fundamental design principle for next-generation catalysts and energy-conversion technologies.
