Identification of the precursor of singlet oxygen (1O2, 1Δg) involved in the disproportionation of hydrogen peroxide catalyzed by calcium hydroxide
Abstract
Catalytic disproportionation of hydrogen peroxide by calcium hydroxide generates singlet molecular oxygen 1O2 (1Δg) through the diperoxohydrate peroxide CaO2·2H2O2 with a 50% yield based on the calcium peroxide.
