Published in 2017 at "Microporous and Mesoporous Materials"

DOI: 10.1016/j.micromeso.2016.02.031

Abstract: Abstract Mesoporous alumina with pseudo-boehmite phase modified by water glass was prepared by using the cation–anion double hydrolysis method from mixed aqueous solution of aluminum sulfate and sodium aluminate. The texture structure and acidity of… read more here.
