Suppressing hydrogen peroxide generation to achieve oxygen-insensitivity of a [NiFe] hydrogenase in redox active films

Oxidative degradation impedes practical applications of highly active but fragile catalysts. Here the authors show that combining a protection matrix for O2 reduction and hydrogen peroxide decomposition stabilizes highly O2-sensitive hydrogenase in the harsh oxidative conditions of operating fuel ce...

Sumario:Oxidative degradation impedes practical applications of highly active but fragile catalysts. Here the authors show that combining a protection matrix for O2 reduction and hydrogen peroxide decomposition stabilizes highly O2-sensitive hydrogenase in the harsh oxidative conditions of operating fuel cells.
