Bimetallic Pd-Co Aerogel Three-Dimensional Architecture: Developing Self-Assembled Materials for Advanced Ethanol Oxidation.

Modern electrocatalysts with unique morphologies have found a special position in sustainable energy-related processes. In this article, an easy, fast, and one-step gelation procedure is introduced to fabricate a three-dimensional Pd-Co aerogel. This engineered aerogel is synthesized by inducing controlled destabilization between the resulting colloidal system from the reduction of metallic ions via sodium borohydride, followed by supercritical carbon dioxide drying.

Iodine/iodide-doped polymeric nanospheres for simultaneous voltammetric detection of p-aminophenol, phenol, and p-nitrophenol.

A sensor was developed for the first time based on polydopamine nanospheres doped with I, I, and IO species (PDA-Iodine), to determine the concentration of p-aminophenol (p-AP), phenol (Ph), and p-nitrophenol (p-NP) simultaneously. These polymeric nanospheres were successfully characterized using a variety of techniques including field emission scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, Fourier transform infrared, Raman spectroscopy, and X-ray diffraction analysis. A carbon paste electrode was modified with the PDA-Iodine (CPE/PDA-Iodine).

Porous 3D Inorganic Superstructure of Pd-Ir Aerogel as Advanced Support-Less Anode Electrocatalyst toward Ethanol Oxidation.

For the first time, synthesis of Pd-Ir aerogel is reported in this manuscript. The Pd-Ir aerogel is synthesized using the controlled assembly of nanoparticles (NPs) (Ir and Pd) during the facile, surfactant-free, fast, and one-step gelation process in an aqueous environment followed by CO supercritical drying. In this process, no chemical reagents are employed to induce the gelation, and change of temperature is employed to create anisotropic electrostatic repulsions between NPs.

An environmentally friendly one-pot synthesis method by the ultrasound assistance for the decoration of ultrasmall Pd-Ag NPs on graphene as high active anode catalyst towards ethanol oxidation.

An environmentally friendly one-pot synthesis approach for the decoration of Pd-Ag nanoparticles with the ultrasmall size on graphene (Pd-Ag/G) by the assistance of ultrasound is proposed in this paper. This method offers exceptional advantages over other approaches such as environmentally friendly synthesis, being low temperature, reductant, surfactant free, simple, fast and one-pot synthesis. In this work, silver formate is added to the graphene suspension at 25 °C.

Sonochemical synthesis of high-performance Pd@CuNWs/MWCNTs-CH electrocatalyst by galvanic replacement toward ethanol oxidation in alkaline media.

In this paper, a fast and effective method for the palladium (Pd) wire nanostructures synthesis with the great surface area through galvanic replacement reaction utilizing copper nanowires (CuNWS) as a template by the assistance of ultrasound under room temperature condition is proposed. A multifunctional catalyst with the mentioned nanostructure, Pd@CuNWs, and multi walled carbon nanotubes (MWCNTs) and chitosan (CH) as a binder was fabricated. To investigate the morphology and bulk composition of the prepared catalyst, Field Emission Scanning Electron Microscopy (FE-SEM), Energy Dispersive X-ray Spectroscopy (EDS), X-ray Powder Diffraction (XRD), and Inductively Coupled Plasma atomic Emission Spectroscopy (ICP-AES) were utilized.

Porous three-dimensional network of Pd-Cu aerogel toward formic acid oxidation.

New self-assembled architectures have received great interest in nanotechnology, and are a highly desired target in recent studies. Among self-assembled architectures, noble metal aerogels are an important class owing to their collective characters as well as widespread applications. The synthesis of noble metal aerogels still faces several obstacles such as long hydrogel creation time and complicated multistep strategies.
