“…Thus we believe that GA could serve as a reducing agent for the reduction of Pd 2+ to form PdNPs. With the use of GA, the synthesis of PdNP colloids is so simple that no surfactant, photo-irradiation, or heat treatment is required [6,7]. The preparation of GA-PdNP colloids is so efficient that the synthetic process can be completed within 5 min, which shows great practical value for the large-scale preparation of PdNP colloids.…”

A facile, eco-friendly, room-temperature method for rapid one-pot synthesis of Pd metallic nanoparticles has been developed based on the successive reduction of Pd(II) precursors with gallic acid in an aqueous environment. The morphology and surface analysis of the resulting Pd nanoparticles were confirmed by aberration corrected scanning transmission electron microscopy followed by X-ray photoelectron spectroscopy. The particle size of palladium nanoparticles was calculated as 16 nm. This study demonstrates that the synthesis of nanoparticles (reduction and stabilization) can be effectively achieved using gallic acid.

“…Utilizing the different reduction potentials of different metal precursors, bimetallic core-shell structure could be prepared by one-pot synthetic process [75,76]. However, it is still a challenge to control this process since alloys or heterostructures with uncontrolled morphologies are usually produced.…”

Noble metal-based nanocomposites are attractive for a rich variety of electrocatalytic applications as they can exhibit not only a combination of the properties associated with each component but also synergy due to a strong coupling between different constituents. Using noble metal as the base component, a plenty of methods have been recently demonstrated for the synthesis of noble metal-based nanocomposites with novel structures (e.g., alloys, core-shell, skin and 1D/2D structures). In this chapter, an account of recent advances of synthetic approaches to noble metal-based nanocomposites with controlled structures, compositions and sizes are reviewed. The relationship between structures and electrochemical properties of these nanocomposites in fuel cell field is discussed. The potential future directions of research in the field are also addressed.

“…For example, Han and co-workers reported a one-step aqueous synthesis of Au/Pd core-shell NPs with a well-defined octahedral shape (Figure 15). [128] Figure 15 a shows a representative SEM image of the prepared sample, which demonstrates that the sample was composed of octahedral NPs. A high-resolution TEM image (Figure 15 b) clearly confirms the core-shell structure of the octahedral NPs.…”

Nano-heterostructures have attracted great attention due to their extraordinary properties beyond those of their single-component counterparts. This review focuses on a specific type of hybrid structures: core-shell structures. In particular, we present and discuss the recent wet-chemical synthesis approaches for semiconductor and metallic core-shell nanostructures, and their relevant properties and potential applications in photovoltaics and catalysis, respectively.

One-Step Synthesis of Au@Pd Core−Shell Nanooctahedron

Abstract: Octahedral Au@Pd core-shell nanoparticles have been prepared by a one-step aqueous synthesis method where both metal precursors are present simultaneously with the use of cetyltrimethylammonium chloride as both reductant and stabilizer.
