Recent progresses in the adsorption of organic, inorganic, and gas compounds by MCM-41-based mesoporous materials

Current State of Porous Carbon for Wastewater Treatment

“…In this category of materials, the pore diameter varies between 2 and 50 nm (2 nm < d p < 50 nm). A distinction is made between crystalline mesoporous materials and ordered amorphous materials, which are intermediate between that of crystalline microporous solids of the zeolite type and disordered amorphous solids such as silica gel [35][36][37]. Mesoporous materials have several known applications such as catalysis, filtration, pollution control, optics, and even electronics.…”

Magnetic Fe3O4@SiO2–Pt and Fe3O4@SiO2–Pt@SiO2 Structures for HDN of Indole

“…The isotherm exhibits two distinguished inflections in the adsorbed amount. The first one at P/P 0 = 0.4–0.6 is attributed to the pores created after CTAB micelles removal [36,37], and the second one at P/P 0 close to 0.8 which can be ascribed rather to the effect of interparticle voids present between some coalesced aggregates of the material [38]. The pore size distribution shows a bimodal distribution with a narrow distribution centered at 3.8 nm and a wider distribution centered at 14 nm associated with the interstitial spaces of the aggregates of the particles.…”

Fe3O4@MCM‐41@ZrCl2: A novel magnetic mesoporous nanocomposite catalyst including zirconium nanoparticles for the synthesis of 1‐(benzothiazolylamino)phenylmethyl‐2‐naphthols

“…In spite of significant advances in the field of mesoporous materials and the growing expansion of new types of them, [1][2][3][4][5][6][7][8] the first and foremost member of M41S called MCM-41 still has attracted growing research attention owing to its chemical versatility. [9][10][11][12][13] Its capabilities, especially in the field of catalytic activity, all come from its unique properties, such as high surface area ($1000 m 2 g −1 ), narrow pore size distribution, uniform pore size, and the possibility of adjusting the diameter of the pores between 2 and 10 nm. These features result in high thermal stability and the possibility of using it in a wide range of applications such as catalization, [13][14][15] isolation, [16][17][18] photocatalysis, [19][20][21] sensors, [22][23][24] absorption, [25][26][27] and so forth.…”
