Nonuniform catalyst distribution for inorganic membrane reactors: Theoretical considerations and preparation techniques

Fabrication of Pd@ZIF-8 catalysts with different Pd spatial distributions and their catalytic properties

“…ZIFs are particularly promising as supports for metal nanoparticles (MNPs) immobilization [4][5][6]. Generally, MNPs with high surface energy tend to aggregate during reactions, resulting in the deactivation of MNP catalysts [7][8][9][10]. Therefore, inhibiting the agglomeration of MNPs throughout the catalytic reactions depends on some fabrication strategies.…”

Improved catalytic stability of PtSnIn/xCa–Al catalysts for propane dehydrogenation to propylene

“…Pt-based catalysts attract much attention because of its high catalytic performance and eco-friendly property [5,6]. Additionally, several reactors including fixed bed reactor, fluidized bed reactor and membrane reactor are employed to the light alkanes dehydrogenation reactions [7][8][9].…”

Preparation of core (Ni base)–shell (Silicalite-1) catalysts and their application for alkali resistance in direct internal reforming molten carbonate fuel cell

“…There are also significant efforts in developing alkali-resistant catalysts including Ru/ZrO 2 [12] and Ni catalysts supported on alkali-resistant ␥-LiAlO 2 [13], MgO-TiO 2 [14] and MgO-Al 2 O 3 [15]. A nonuniform catalyst distribution can also ameliorate the effects of poisons by locating the catalysts in an interior location of the pellet [16][17][18][19].…”
