Mesoporous Core–Shell Pd@Pt Nanospheres as Oxidase Mimics with Superhigh Catalytic Efficiency at Room Temperature

“…High-resolution XPS spectra indicate that Pt and Pd are primarily in the form of Pt(0) and Pd(0) (Figure S6). 12,34 The above results imply the successful synthesis of mesoporous nanospheres with a Pd core and Pt shell.…”

“…The atomic ratio of elemental Pt to Pd in mPd@Pt NSs was determined to be ∼1:2 by inductively coupled plasma mass spectrometry (ICP-MS). The diffraction peaks in the X-ray diffraction (XRD) pattern (Figure E) was assigned to (111), (200), (220), (311), and (222) diffractions of the fcc metal . The X-ray photoelectron spectroscopy (XPS) analysis showed that Pt 4f and Pd 3d peaks were clearly seen from mPd@Pt NSs.…”

Simple Synthesis of PdAg Porous Nanowires as Effective Catalysts for Polyol Oxidation Reaction

“…It has been confirmed that the electrocatalysis of Pd-based catalysts for EGOR and GOR can be optimized by adjusting the morphology of catalysts. − The catalytic properties of hollow, spherical, tubular, sheet, and gridlike Pd-based nanomaterials for EGOR and GOR have been reported and studied. − Among them, Pd-based hollow catalysts have been widely studied benefiting from the geometric effect of the hollow structure. Pd-based nanomaterials exhibit excellent catalytic performance because their hollow structures utilize large internal void spaces and surface pores to optimize the specific surface area and increase their active sites. , Pd-based catalysts can also increase their surface area by increasing their surface roughness, thereby further improving their catalytic performance.…”

Ultrathin and Porous 2D PtPdCu Nanoalloys as High-Performance Multifunctional Electrocatalysts for Various Alcohol Oxidation Reactions

“…It is recognized that the d -band center will be upshifted by alloying Pt with other metals, − suggesting that the electrocatalytic activity can be effectively improved through introduction of other components. To date, Pd, Zn, Co, Ag, Mn, Au, Sn, Ru, Cu, and so forth have been incorporated into the Pt matrix. − Furthermore, the introduction of oxophilic metals can also facilitate the removal or oxidation of poisoning CO intermediates formed on the Pt surface, − leading to enhancement in both the activity and stability. Based on the alloys, multimetals offer a good opportunity to optimize their catalytic properties via varying their atomic ordering. , Apart from the alloy composition, morphology engineering of the Pt-based electrocatalysts serves as another powerful method to booster their catalytic performances. − Among various nanocrystals available, the metal nanostructures with a porous architecture have received great attention in electrocatalysis due to their large surface area and thus abundant active sites during catalytic reactions. − Moreover, the Ostwald ripening effect can be suppressed owing to the interconnected structures existing in the porous nanostructures, leading to a high electrocatalytic performance .…”
