Palladium nanoparticles encapsuled in MOF: An efficient dual-functional catalyst to produce benzylmalononitrile derivatives by one-pot reaction

Pd NPs decorated on crosslinked sodium alginate modified iron-based metal–organic framework Fe(BTC) as a green multifunctional catalyst for the oxidative amidation

“…In the XRD spectrum of Fe(BTC)@SA/ED/Pd, slight shis in position and width were observed, along with a few intense peaks in the 2q angles of 25°-45°, indicating the presence of sodium alginate in the nanocatalyst. 44 Additionally, sharp peaks at 2q angles of 30.96°, 55.17°, and 66.30°conrm the successful synthesis of Pd NPs on the surface of Fe(BTC) @SA/ED 45,46 (Fig. 6b).…”

Carboxamide functionality grafted entangled Co(ii) framework as a unique hydrogen-bond-donor catalyst in solvent-free tandem deacetalization-Knoevenagel condensation with pore-fitting-mediated size-selectivity

“…However, acidic and basic sites in a single system are highly prone to neutralize and deactivate each other, which forms the challenge of developing bi-functional catalysts with accurately installed antagonistic active motifs. 27 While a handful of reports describe cooperative deacetalization-Knoevenagel condensation, 28–30 most of the reactions are catalysed either via Lewis and/or Brønsted acidic and Lewis basic sites (Scheme 1), and two-point hydrogen-bonding mediated reaction under solvent-free conditions is hitherto unexplored, to the best of our knowledge.…”

Polymelamine Formaldehyde-Coated MIL-101 as an Efficient Dual-Functional Core–Shell Composite to Catalyze the Deacetalization–Knoevenagel Tandem Reaction

“…As a promising catalytic material, metal–organic frameworks (MOFs) are constructed from clusters or metals and organic ligands. , Extensive attention has been paid due to their large specific surface area, adjustable pore size, and large pore size . They have been widely used in gas storage, carbon capture, sensing, and catalysis because of the above characteristics. , For catalytic applications, the high crystallinity and the molecular level design of the structure of MOFs are expected to improve the catalytic selectivity . However, since MOFs have a single catalytic site, when used as a catalyst, it is necessary to modify MOFs with different materials to form composites with multiple catalytic sites. ,, MOF-based composites include carbon nanostructure@MOF, enzyme@MOF, ionic metal NPs@MOF, etc .…”
