Mn2O3 microcubes with three-dimensional porous network structure as electrochemical sensing material for nitrite

Abstract Mn 2 O 3 microcubes with three-dimensional (3D) micromesoporous network structure were synthesized by thermal decomposition of the as-prepared MnCO 3 precursor. The structure, morphology, and textural property of the as-synthesized Mn 2 O 3 microcubes were characterized. The electrochemical property and electrochemical sensing performance toward nitrite detection were investigated. Owing to the unique 3D micromesoporous network structure, the Mn 2 O 3 microcubes could provide electrochemical sensing of nitrite with high sensitivity, selectivity, and reliability.
