Synthesis and capacitive property of hierarchical hollow manganese oxide nanospheres with large specific surface area
The hierarchical hollow manganese oxide nanospheres with both a large surface area and a layered structure have been successfully prepared by a templating-assisted hydrothermal process at 150 °C for 48 h. SiO 2 template spheres are dispersed in KMnO 4 solution, and then followed by hydrothermal trea...
