Acid hybrid catalysts from poly(styrenesulfonic acid) grafted onto ultra-large-pore SBA-15 silica using atom transfer radical polymerization

Abstract: Poly(styrenesulfonic acid)-functionalized materials based on poly(styrenesulfonic acid sodium salt) incorporated via aqueous atom transfer radical polymerization (ATRP) initiated from the surface of large-pore mesoporous SBA-15 silica support have been synthesized. The inorganic-organic nature of these hybrid materials makes them particularly desirable for acid-catalyzed reactions that require extended and hydrophobic surface areas with a narrow pore diameter distribution in the mesoporous range. Acidic hybrid… Show more

“…These rate enhancements are attributed to superior mass transport of the bulky FFA and triglycerides within the expanded PrSO 3 -SBA-15. Similar observations have been made over Poly(styrenesulfonic acid)-functionalised ultra-large pore SBA-15 in the esterification of oleic acid with butanol [81].…”

“…Thus, these particles are good candidates for example controllable drug release applications, 10 catalysis, 11,12 or magnetic resonance imaging. 13 In grafting nanoparticles with polymers, surface initiated atom transfer radical polymerization (SI-ATRP) technique is often the method of choice due to its versatility.…”

“…styrenesulfonic acid grafted by this route on SBA-15 silica appeared to be an active catalyst of esterification processes [55,56]. Although there are a few papers dealing with using the ATRP method for the modification of SBA-15, silica materials exhibiting narrower pores (e.g.…”
