A major drawback is the cost of production, dominated by the quantity of an expensive platinum catalyst required for the oxygen reduction reaction. Recent research indicates promising replacement ...
"This reaction should be observed in the upper atmosphere of Mars." Scientists have discovered a new way oxygen can form in carbon-dioxide-rich atmospheres of worlds beyond our own ...
An electrocatalytic oxygen reduction reaction (ORR) is a safe, clean, and reliable method, but an effective catalyst has yet to be identified and adopted widely because of low selectivity.
