The role of the manganese average oxidation state (AOS) in water oxidation catalysis by birnessite was investigated.
Our results show that nano-sized gold has no significant effect on the water-oxidation activity of the Mn oxide phase in the presence of Ce(iv).
Self-decorated Mn2O3 nanocrystals on Geobacter sulfurreducens were synthesized as sustainable and efficient water oxidation catalysts.
The bite angle matters: Opening up the O–Ru–O angle of Ru complexes enables water oxidation catalysis.
