“…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].…”

Concerns over the economics of proven fossil fuel reserves, in concert with government and public acceptance of the anthropogenic origin of rising CO 2 emissions and associated climate change from such combustible carbon, are driving academic and commercial research into new sustainable routes to fuel and chemicals. The quest for such sustainable resources to meet the demands of a rapidly rising global population represents one of this century's grand challenges. Here, we discuss catalytic solutions to the clean synthesis of biodiesel, the most readily implemented and low cost, alternative source of transportation fuels, and oxygenated organic molecules for the manufacture of fine and speciality chemicals to meet future societal demands.

“…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.…”

Mesoporous silica particles were grafted with thermoresponsive poly (ethyleneoxide-b-N-vinylcaprolactam), PEO-b-PVCL. N-vinylcaprolactam was first polymerized on particle surfaces using surface initiated atom transfer radical polymerization (SI-ATRP) and then, the poly(ethyleneoxide) blocks were attached to the PVCL chain ends with click chemistry. The sizes, thermoresponsiviness, and colloidal stability of SiO 2 -PVCL and SiO 2 -PVCL-b-PEO particles and their aqueous dispersions were studied by scanning electron microscopy, turbidimetry, dynamic light scattering, zeta sizer, and microcalorimetry. The phase separation temperature of the PEO-b-PVCL grafted particles did not considerably differ from that of the SiO 2 -PVCL particles. The zeta potential of the grafted particles was close to zero at room temperature but decreased strongly upon heating. The decrease is related to the collapse of the PVCL blocks and correspondingly, the exposure of the silica surface toward the aqueous phase. The colloidal stability of the particles could be enhanced by adding PEO blocks to the chain ends of the PVCL grafts.

“…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.…”

Investigation on the Low-Temperature Transformations of Poly(furfuryl alcohol) Deposited on MCM-41

MCM-41-type mesoporous silica was used as a support for poly(furfuryl alcohol) deposition. This material was produced by precipitation-polycondensation of furfuryl alcohol (FA) in aqueous slurry of the SiO 2 support followed by controlled partial carbonization. By tuning the FA/MCM-41 mass ratio in the reaction mixture, various amounts of polymer particles were introduced on the inner and outer surface of the MCM support. The thermal decomposition of the PFA/MCM-41 composites was studied by thermogravimetry (TG) and spectroscopic techniques (DRIFT, XPS), whereas the evolution of textural parameters with increasing polymer content was investigated using low-temperature adsorption of nitrogen. The mechanism of thermal transformations of PFA deposited on the MCM-41 surface was discussed in detail. It was found that heating at a temperature of about 523 K resulted in opening of the furan rings and the formation of γ-diketone moieties, which were found to be * Corresponding author.

A further increase in calcination temperature caused a drop in the amounts of surface carbonyls and the appearance of condensed aromatic domains.
