Structural Analysis and Electrochemical Properties of Bimetallic Palladium-Platinum Aerogels Prepared by a Two-Step Gelation Process

Journal Article Oezaslan, Mehtap ; Herrmann, Anne-Kristin ; Werheid, Matthias ; ... - ChemCatChem

Multimetallic aerogels have emerged as promising unsupported and high-surface-area metal materials for different applications in heterogeneous catalysis and electrochemistry, which are fabricated using a gelation process characterized by the controlled aggregation of metallic nanoparticles to form a macroscopic network structure in aqueous solution. However, the achievement of the structural homogeneity of the multimetallic aerogels in terms of the diameter of the nanochains and the chemical composition at the nano- and the macro-scale is still a great challenge. In this paper, we investigated two Pd-Pt aerogels prepared by the two-step gelation method. The structural homogeneity and chemical distribution of both metalsmore »« less

Delicately engineering the well-defined noble metal aerogels with favorable structural and compositional features is of vital importance for wide applications. Here, we reported one-pot and facile method for synthesizing core-shell PdPb@Pd hydrogels/aerogels with multiply-twinned grains and ordered intermetallic phase using sodium hypophosphite as a multifunctional reducing agent. Due to the accelerated gelation kinetics induced by increased reaction temperature and specific function of sodium hypophosphite, the formation of hydrogels can be completed within 4 hrs, far faster than the previous reports.

Oxidative Self-Assembly of Au/Ag/Pt Alloy Nanoparticles into High-Surface Area, Mesoporous, and Conductive Aerogels for Methanol Electro-oxidation

Journal Article Sarkar, Rajib ; Farghaly, Ahmed A. ; Arachchige, Indika U. - Chemistry of Materials

The ability to assemble nanoparticles (NPs) into functional nanostructures is critical for the advancement of nanoscience. However, common assembling techniques utilize organic ligands or biomolecules, which are detrimental for charge transport and interparticle coupling, which impede the efficient integration of low-dimensional properties. Herein, we report a methodology for the self-supported assembly of ultra-small (3-6 nm) Au/Ag/Pt alloy NPs into large, free-standing alloy superstructures (aerogels) that exhibit direct NP connectivity, high surface area (125 ± 0.43 to142 ± 0.93 m²/g) and mesoporosity (21.6 ± 2.2 nm), and superior electrocatalytic activity for methanol oxidation reaction (MOR).

Quantitative Analysis of the Reduction Kinetics Responsible for the One-Pot Synthesis of Pd–Pt Bimetallic Nanocrystals with Different Structures

Journal Article Zhou, Ming ; Wang, Helan ; Vara, Madeline ; ... - Journal of the American Chemical Society

We report a quantitative understanding of the reduction kinetics responsible for the formation of Pd–Pt bimetallic nanocrystals with two distinctive structures. The syntheses involve the use of KBr to manipulate the reaction kinetics by influencing the redox potentials of metal precursor ions via ligand exchange. In the absence of KBr, the ratio between the initial reduction rates of PdCl₄^2– and PtCl₄^2– was about 10.0, leading to the formation of Pd@Pt octahedra with a core–shell structure. In the presence of 63 mM KBr, the products became Pd–Pt alloy nanocrystals. In this case, the ratio between the initial reduction rates of themore »« less
