Abstract: Catalytic materials useful, e.g., in water oxidation performing at low overpotential and/or stable for applications such as solar-to-fuel conversion systems may include nanoscale, nanoporous Pd-containing materials. Thin-film Pd electrocatalysts may be obtained via Aerosol-Assisted Chemical Vapor Deposition (AACVD) on conducting surfaces. XRD and XPS analyses show a phase pure crystalline metallic Pd deposit. Surface morphology study reveals a nanoparticulate highly porous nanostructure. Under electrochemical conditions, such Pd electrocatalysts may conduct water oxidation at onset potentials starting around 1.43 V against a reversible hydrogen electrode (ηof 200 mV, Tafel slope of 40 mV/dec), and/or may achieve around 100 mA/cm2 current density at 1.63 V against a reversible hydrogen electrode, and may exhibits long-term stability in oxygen evolution. Method of making such electrocatalysts and their uses are also provided.

Abstract: A method of making a nanostructured palladium thin film electrode is described. The method involves contacting a substrate with an aerosol comprising a solvent and a Pd(II) compound. The substrate is heated, and no hydrogen gas or an additional reducing agent is required to reduce the Pd(II) to form the deposited thin film. The nanostructured palladium thin film electrode is capable of detecting compounds such as hydrazine in an aqueous sample with a 10 nM limit of detection.
