Metal-nanoparticles Supported on Solid as Heterogeneous Catalysts

A novel heterogeneous nanocatalyst: 2‐Methoxy‐1‐phenylethanone functionalized MCM‐41 supported Cu(II) complex for C‐S coupling of aryl halides with thiourea

“…Moreover the metal nanoparticles grafted onto supports are more effective because of unmatched one‐, two‐ or three‐ dimentional morphological properties and high surface to volume ratio compared with the catalysts based on accumulated metal particles …”

Copper Nanoparticles Stabilized in a Porous Chitosan Aerogel as a Heterogeneous Catalyst for C−S Cross‐coupling

“…The stabilization of metastable metallic entities against aggregation, with the minimal alteration of the intrinsic catalytic activity, is one of the key points to design highly durable reactive MNPs. Generally, this fundamental prerequisite can be attained by confining MNPs in porous solid supports, wherein the limited available space in the cavities impedes MNP growth and possible interactions with the support may prevent metal leaching from the solid to the liquid phase …”

Water-dispersible Fe3O4 nanowires as efficient supports for noble-metal catalysed aqueous reactions

“…Supported-metal catalysts are among the most important materials in heterogeneous catalysis. [1][2][3][4] Many industrial catalysts consist of noble metals dispersed on high-area porous supports. Their catalytic performance strongly depends on the chemical nature and physical structure of the supports.…”
