In contrast, the Mn SP 3 sp -poor MnPi lacks sufficient active sites and is inefficient for the oxygen reduction reaction. Front Cover: Mn3 -rich Manganese Phosphate Targeted for Enhanced Oxygen Reduction Reaction in Zinc-Air Batteries (ChemNanoMat 11/2022) B A pre-oxidation-precipitation b strategy is adopted to construct Mn SP 3 sp -rich manganese phosphate nanosheets (Mn SP 3 sp -rich MnPi), which could afford abundant active sites and accelerate the kinetic process for the oxygen reduction reaction.
