Hybrid Mesoporous Silica/Noble-Metal Nanoparticle Materials—Synthesis and Catalytic Applications

Abstract: Due to the uniform and stable pore structure, mesoporous silica has attracted increasing research attention as a catalyst support material. As a large family of mesoporous silica-supported materials, noble-metal nanoparticles supported on mesoporous silica catalysts have demonstrated desirable properties across a broad platform of reactions. In this review article, we first introduce systems of metal nanoparticles dispersed on mesoporous silica, and then, we focus on next generation systems, in which the noble… Show more

“…According to reports, as well as aluminum, noble and base metal ions (such as Pt, Ru, Rh, Ni, Co, Ag, and Cu) can be incorporated into mesostructured silica and aluminosilicates. [64][65][66][67][68] It is worth mentioning that the characteristics, especially the acid strengths of the sites, of DLCT aluminosilicates highly depend on the Si : Al ratio, however, the acid strengths at all Si : Al ratios are greater than in MCM-41 materials. This characteristic is a matter of interest in catalysis, where a requirement is the presence of medium acid strength.…”

“…It is advisable to use non‐aqueous solvents like toluene for the functionalization of silica with amine groups. Because the unsolicited hydrogen bonding occurring between amine groups and solvent molecules hinders the efficiency of functionalization In post‐synthetic functionalization, silica prepared by low temperature methods (E.g.…”

“…8,9 Moreover, the complete separation of ligand-stabilized NPs aer catalysis is rather difficult, leading to a limited recyclability of the NPs. 10 One strategy to overcome these issues is the immobilization of NPs on a solid inorganic support, like (porous) metal oxides and silica, [11][12][13][14][15] nano-tubes and -rods, [16][17][18] or two-dimensional layered materials like graphene or graphitic carbon nitride. [19][20][21] An interesting approach is the use of magnetic iron oxide NPs as a support, facilitating an easy recovery of the catalyst by applying a magnetic eld.…”
