Pd nanoparticles encapsulated into mesoporous ionic copolymer: Efficient and recyclable catalyst for the oxidation of benzyl alcohol with O2 balloon in water

Nanoscale Pd supported on 3D porous carbon for enhanced selective oxidation of benzyl alcohol

“…8, the peaks at 335.5 AE 0.2 eV corresponded to Pd(0), and the other peak at 337.45 eV indicated the formation of Pd-O bonds. 25,26 The intensity of the peaks suggested that majority of the Pd nanoparticles are Pd(0), and that Pd also exists in the catalysts in the form of Pd(II), which can easily bond with the O atom. As shown in Fig.…”

Porous Polyelectrolytes: The Interplay of Charge and Pores for New Functionalities

“…[104] Theg roups of Wang,[69c] Xiao, [69e] and Bordiga [69b] copolymerized several IL monomers with divinylbenzene to prepare mesoporous PILs that function as asolid-liquid heterophase catalyst. Interestingly,these mesoporous PILs have good accessibility to organic compounds and resistance to CO 2 /H 2 O. Thec atalytic function of the porous PIL family was further expanded by loading with palladium nanoparticles or a-CuV 2 O 6 nanobelts for the oxidation of benzyl alcohol [105] or the direct catalytic synthesis of 2,5-diformylfuran from fructose, [106] respectively.…”

A Ca(II) Coordination Polymer of 2-Carboxybenzaldehyde: Synthesis, Crystal Structure, and Catalytic Activity in Oxidation of Benzyl Alcohol

“…3% Au-Hal-2 catalysts showed good benzyl alcohol conversion (79%) and high benzaldehyde selectivity (above 97%) in the benzyl alcohol oxidation with 10 bar of O 2 at 100 • C under magnetic stirring. Wang et al [33] prepared palladium nanoparticles (PdNPs) supported on functional cross-linked mesoporous poly(ionic liquid)s (MPILs) (Pd@MPIL) through NaBH 4 reduction route. The obtained materials showed good benzyl alcohol (96%) and benzaldehyde selectivity (99%) by using O 2 as the oxidant and water as the sole solvent at low temperature (90 • C) with K 2 CO 3 as additive.…”
