Construction of ternary methoxy hydroxide M(OH)(OCH ₃ ) (M = Co, Cu, Mn) with a flower-like structure for highly efficient electrocatalytic oxygen evolution

Flower-like M(OH) (OCH ₃ ) (M = Co, Cu, Mn) nanosheets were grown in situ on Fe foam by one-step hydrothermal synthesis, requiring only 215 and 360 mV to reach 20 and 100 mA cm ⁻² , respectively.
