Facile Synthesis of Mesoporous MnCO₃ for Supercapacitor Applications.

We report a rapid and facile synthesis of MnCO3 with uniform mesopores for supercapacitor applications. Mesoporous MnCO3 was synthesised by a co-precipitation method using MnSO4 and (NH4)HCO3 as manganese and carbonate source, respectively. Powder X-ray diffraction study confirmed the formation of rhodochrosite phase of MnCO3.
