Abstract: Abstract Organosulfonic acid functionalized montemorillonite-MMT (K10 and cloisite Na+) were prepared by different methodologies: (a) one-pot organosilylation or sulfonation, and (b) two-step organosilylation followed by sulfonation or oxidation. The physicochemical characterization ensured the success of… read more here.
