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

Recent Advances on the Design of Group VIII Base-Metal Catalysts with Encapsulated Structures

“…63 Moreover, Ni-based catalysts encapsulated by zeolite shells (MSU-1 and Sil-1) also performed excellent activity in methane steam reforming for hydrogen production. 64,65 2.2 Core@tube Structures. Different from core@shell and yolk@shell structures, core@tube composites are materials in which the highly dispersed metal NPs are confined by well-defined channels of nanotubes.…”

The SiO2 supported bimetallic Ni–Ru particles: A good sulfur-tolerant catalyst for methanation reaction

“…In addition to the direct exploitation of natural gas, the catalytic conversion of stoichiometric syngas (H 2 + CO) into methane (the so-called synthetic natural gas (SNG)) provides a promising way to supply this clean fuel in the area with few resource of natural gas [1][2][3][4][5][6][7][8][9]. Moreover, this SNG process has also been applied to remove trace CO molecules to purify the hydrogen for the fuel cell and the ammonia synthesis [10,11].…”

Facile preparation of ZIF-8@Pd-CSS sandwich-type microspheres via in situ growth of ZIF-8 shells over Pd-loaded colloidal carbon spheres with aggregation-resistant and leach-proof properties for the Pd nanoparticles

“…Another alternative and promising approach is to encapsulate the metal nanoparticles-loaded materials within a different kind of porous shell to form a sandwiched structure, where the function of the outer shell is twofold: stabilizing the metal nanoparticles against aggregation and leaching, and providing synergic effects such as resistance to poisoning and regulation of diffusion. Examples of this approach include novel synthesis of mSiO 2 @SiO 2 -Au@Fe 3 reported by Deng et al [10] and Ge et al [11], and preparation of Sil-1@Ni-Al 2 O 3 core-shell particles described by our previous work [12].…”
