Application of gold and palladium nanoparticles supported on polymelamine microspheres in the oxidation of 1-phenylethanol and some other phenyl substituted alcohols

Gemini surfactant‐stabilized Pd nanoparticles: Synthesis, characterization, and catalytic application in the reduction and reductive acetylation in the water solvent

“…34 The Tauc plot of these NPs showed a direct allowed transition band gap of 4.40 eV, suggesting better quantum confinement of Pd-L4 NPs and their smaller size (1-40 nm) (Figure 2a). 35 diffraction peaks at 2θ = 14.1 and 23.6 . These reflections may be due to the existence of long chain organic phase (Figure 2b).…”

“…The Tauc plot of these NPs showed a direct allowed transition band gap of 4.40 eV, suggesting better quantum confinement of Pd‐ L4 NPs and their smaller size (1–40 nm) (Figure 2a). 35 The powder‐X‐ray diffraction (PXRD) analysis of active catalyst Pd‐ L4 NPs indicated characteristic diffraction peaks correspond to simple cubic Pd phase (JCPDS: 00‐032‐1593; d (nm): 0.34; a = b = c (nm): 0.39; α = β = γ = 90°; ρ (Mg m −3 ): 12.38; V (nm 3 ): 0.060) with a crystallite size of 46.3 nm, along with low intensity diffraction peaks at 2θ = 14.1° and 23.6°. These reflections may be due to the existence of long chain organic phase (Figure 2b).…”

Bridging and terminal hydroxyl groups of Zr(OH)4 as active sites for the ultraselective transformation of biomass-based alcohols

“…This creates a serious economic burden restricting their industrial applications. [25][26][27][28][29][30] As for the dehydration of 1-phenyethanol, most reported works are based on acid catalysts or acids causing equipment corrosion and environmental pollution. [31][32][33][34][35] In addition, due to the different reaction mechanisms of the formation of acetophenone and styrene from 1-phenylethanol, using the same catalyst for regulating the selectivity of the two reactions is a great challenge and has not been reported.…”

Tuning Ni‐Pyrazolate Frameworks by Post‐Synthetic Fe‐Incorporation for Oxidase‐Mimicking H2O2 Activation

“…[13,14] In order to overcome the limitations of homogeneous catalysis, heterogeneous catalysts containing noble metals have been traditionally employed in the oxidation of alcohol to carbonyl compounds. [15,16] Recently, Earth-abundant metals, such as Fe, have been well-isolated in silicates as high-performant heterogeneous catalysts for alcohol oxidations using aqueous H 2 O 2 solutions. [17,18] Moreover, iron (III)-MOFs, such as the MIL-100(Fe), have been also tested for alcohol oxidation in different works [19,20] and Fe-MOF-74 was proved for phenol hydroxylation reaction.…”
