Abstract

In this paper

through calcining the ellipsoid-like MnCO

precursors at 500°C

the ellipsoid-like

ε-

MnO

catalysts with an excellent property to decompose methylene blue can be obtained.

ε-

MnO

is measured by SEM

XRD

UV-Vis and BET. The results show that the ellipsoid-like

ε-

MnO

catalysts possess a high surface area of ca.88 m

/g. The obtained ellipsoid-like

ε-

MnO

materials are used as catalysts to decompose methylene blue in the present property of H

.And the ellipsoid-like

ε-

MnO

can remove about 92% of methylene blue

which shows excellent property to remove methylene blue at room temperature

. This shows that ellipsoid-like

ε-

MnO

is a highly efficient catalyst removal of methylene blue.
