Facile size-controllable synthesis of single crystalline \b{eta}-MnO2 nanorods under varying acidic strengths

Abstract

A simple one-pot hydrothermal synthesis of single crystalline beta-MnO2 nanorods with diameters in the range of 10-40nm is reported. During the synthesis process, the acid molarities were varied from 1.1M down to 0.2M in steps of 0.3M while keeping the other reaction parameters constant, resulting in gradual transformation of the size of beta-MnO2 from micro to the nanoscale dimension. The as-synthesized nanorods exhibit soft ferromagnetic behavior and possess a high catalytic activity with an onset potential of -0.17V in facilitating the oxygen reduction reaction (ORR).
