Manganese Oxide Prepared By Ballmilling

Manganese oxide integrated catalytic ceramic membrane for

Dec 15, 2019· In addition, the pure alumina ceramic membrane supports were made by the same procedure without the addition of any manganese oxides when ball-milling. The photos of the pure alumina ceramic membrane support and Mn-1, Mn-3 and Mn-6 membranes are shown in Fig. S1 (a), and the size of membrane disc is displayed in Fig. S1 (b) and (c). 2.4.
