摘要Abstract: In this study, adding NaOH and manganese acetate (Mn(CH3COO)2) solution for the precursor, and cationic surfactant cetyltrimethyl ammonium brombide (CTAB) as a template to use their self-assembly characteristics,so that the precursor were attached to CTAB, prepared manganese oxide powder. By changing the weight percentage of CTAB solution, the surface of different types of manganese oxide. The use of XRD, SEM analysis of the structure of the manganese oxide and the surface patterns. The results showed that adding 15 wt% CTAB solution in the synthesis, there are α-Mn2O3 and Mn3O4 two-phase coexistence. With the increase in the concentration of CTAB added (30wt%), as (550oC) after calcination, α-Mn2O3 phase also increased.The pore
structure can be formed of truncated-octahedal manganese oxide crystal patterns.
