Biomimetic di-manganese catalyst cage-isolated in a MOF: robust catalyst for water oxidation with Ce(<scp>iv</scp>), a non-O-donating oxidant

Abstract

A biomimetic di-Mn catalyst catalyzes water oxidation with (NH4)2Ce(NO3)6 for >7 days with initial TOF of 40 h−1. Isolation of one molecule of catalyst in each pore of a Cr-based MOF prevents decomposition of the catalyst and allows sustained water oxidation even at pH 1.00.
