Abstract
Mesoporous manganese oxide (MPMO) K0.216MnO2 ⋅ 1.26H2O was synthesized by reduction of KMnO4 with maleic acid. Its composition and structure were analyzed and characterized by inductive coupled plasma atomic emission spectrometry (ICP-AES), titration, X-ray powder diffractometry (XRD), thermogravimetry (TG)-differential thermoanalysis (DTA). The morphology and pore structure of the MPMO material were accomplished by means of high-resolution transmission electron microscopy (HRTEM) and N2 sorptometry and transmission electron microscopy (TEM). The results show that MPMO is a pseudocrystalline material with complex network pore structure; its BET surface area is 261.6 m2/g and pore diameter distribution is approximately in the range of 2–10 nm. The MPMO material turns into α-MnO2 when the calcinating temperature rises to 400°C.
