'Green' batteries made to last: Oxide/carbon composite outperforms expensive platinum composites

An oxide/carbon composite outperforms expensive platinum composites in oxygen chemical reactions for green energy devices. Electrochemical devices are crucial to a green energy revolution in which clean alternatives replace carbon-based fuels. This revolution requires conversion systems that produce hydrogen from water or rechargeable batteries that can store clean energy in cars. Now, Singapore-based researchers have developed improved catalysts as electrodes for efficient and more durable green energy devices. - Source
