Controlling pore size distributions of MCM-41 by direct synthesis

Effect of delayed neutralization on the synthesis of mesoporous MCM-41 molecular sieves

“…The wall thickness was determined by the difference between the repeat distance (a,,) and pore size [2,4,9,20]. All of these MCM41 materials have a BET surface area of around 1000 m2 g-l.…”

Dehydration of fructose and glucose to 5-hydroxymethylfurfural over Al-KCC-1 silica

“…The mesoporosity is advantageous when reactant and product molecules are large. Silica mesoporous materials with high surface area and good thermal stability can easily functionalize [4][5][6] . Silica mesoporous materials are generally used as adsorbents, catalysts and catalyst supports [7][8][9][10][11] .…”

“…Morales et al made numerous mesoporous MCM-41 silica comprising ZrO 2 for conversion of glucose to 5-hydroxymethylfurfural [23] . Jiang et al used SO 4 2 − /Ti-MCM-41 catalyst for cellulose dehydration [24] . He and co-workers produced MCM-41 with five different titanium/silica ratios and displayed that these catalysts increase dehydration of cellulose to 5-hydroxymethylfurfural [25] .…”

Electric Field-Responsive Mesoporous Suspensions: A Review

“…The disclosure by Mobil of the M41S family of materials possessing large uniform pore structures, high specific surface areas, and specific pore volumes depending on the channel arrangement, was an important breakthrough in mesoporous materials research [ 39 ]. Although all three phases in the M41S family can be synthesized by varying the reaction conditions slightly, the energetic stability decreases in the order of hexagonal MCM-41 [ 41 , 42 ], cubic MCM-48 [ 43 ] and lamellar phase MCM-50 [ 44 ]. Among the M41S families, MCM-41 type materials have been studied most frequently [ 45 ].…”
