Selective hydrogenation of 1,3-butadiene over Pd and Pd–Sn catalysts supported on different phases of alumina

Effects of alumina phases as nickel supports on deep reactive adsorption of (4,6-dimethyl) dibenzothiophene: Comparison between γ, δ, and θ-alumina

“…The aluminas are widely used as adsorbents, catalysts, and catalysts supports, due to their large specific surface areas, well-defined pore size distributions, stability within a wide temperature range, ability to stabilize and disperse the active phases as well as moderate acidities. There are several reports representing key roles of alumina polymorphs as catalysts supports [14][15][16][17][18][19]. Laurenti et al [20] reported that different polymorphs of alumina in alumina-supported CoMo catalysts resulted in different turnover frequencies (TOF) in HDS of 4,6-DMDBT.…”

Plant‐Mediated Synthesis of Zinc Oxide Supported Nickel‐Palladium Alloy Catalyst for the Selective Hydrogenation of 1,3‐Butadiene

“…The codeposition–precipitation (DP) method produced smaller, uniform, and reproducible Au/Pd particles that outperformed their counterparts produced using coimpregnation in excess solution (IES) in the hydrogenation of 1,3‐butadiene . In addition, Pattamakomsan and co‐workers reported a remarkable improvement in both activity and selectivity in the gas‐phase hydrogenation of 1,3‐butadiene over a Pd‐Sn catalyst supported on mixed‐phase θ/α‐alumina and pure α‐alumina …”

Bimetallic PdAg nanoparticle arrays from monolayer films of diblock copolymer micelles

“…2D-FFT clearly shows features related to diffraction Debye-Scherrer rings assigned to (111) and (002) type planes, which are typical for a facecentered cubic (fcc) crystal lattice and confirms that this particle is metallic (cubic oxide phases of Pd and Ag do not have lattice parameters consistent with the measured ones). [38][39][40][41] The EDX analysis also revealed that the samples treated with O 2 plasma induce a higher inhomogeneity of the Pd/Ag ratio. For the bigger particle at the bottom of Fig.…”
