Preparation of spherical MCM-41 molecular sieve at room temperature: Influence of the synthesis conditions in the structural properties

Elimination of ketone vapors by adsorption on spherical MCM-41 and MCM-48 silicas decorated with thermally activated poly(furfuryl alcohol)

“…The presence of alcohol decreases polarity of reaction mixture and favors a spherical aggregation of micelles. A few representatives of the homologous series of alcohols (such as methanol, ethanol or n-propanol) as well as their various amounts were tested [11,12]. It was found that the formation of spherical micelles requires less amount of alcohol the longer chain it has.…”

Unraveling the Role of Site Isolation and Support for Semihydrogenation of Phenylacetylene

“…SBA‐15 and MCM‐41 have ordered pores arranged in a hexagonal honey‐comb like pattern, respectively, but the size of mesopores in MCM‐41 is less compared to SBA‐15. It is reported that MCM‐41 has high surface area compared to SBA‐15 because of its thinner walls and lower mesopore size . On the other hand, JNC‐1 has higher surface area compared to SBA‐15 because of lower pore size distribution as SBA‐15 was used as a template .…”

“…MCM‐41 : MCM‐41 (Mobil Composition of Matter No.41) was synthesised according to previous report . For the synthesis of MCM‐41, 3 g of CTAB was added to 600 mL of water and stirred.…”

“…It is reported that MCM-41 has high surface area compared to SBA-15 because of its thinner walls and lower mesopore size. [19] On the other hand, JNC-1 has highers urface area compared to SBA-15 because of lower pore size distribution as SBA-15w as used as at emplate. [18] In the overall Scheme of things,w eh oped to utilize these subtle variationsi ns urface area and pore dimensions towards unique catalytic performance.…”

A novel surface modification approach for synthesizing supported nickel phosphide catalysts with high activity for hydrodeoxygenation of benzofuran

“…Siliceous MCM-41 was synthesized using tetraethyl orthosilicate (TEOS) as the silica source and cetyltrimethylammonium bromide (CTAB) as the template, following the procedure as described in the literature [25]. The supports obtained were named MCM-41.…”
