High surface area, nanoscale, mesoporous manganese oxides with controlled solid-pore architectures and method for production thereof

Nanoscale, mesoporous manganese oxide materials aerogels and ambigels are prepared by altering the method for removing pore liquid from manganese oxide gels. By removing pore fluid under conditions where capillary forces are substantially absent, materials exhibiting a desired high mesoporosity and high surface area can be obtained.
