Aggregated Pt–Pd nanoparticles on Nafion membrane for impulsive decomposition of hydrogen peroxide

Abstract

A Pd site initiates hydrogen peroxide decomposition by adsorbing one ‘O’ followed by splitting of O–H bond. Meanwhile, a Pt site finally completes the decomposition process by enabling desorption of the incipient O2 species.

Composite Noble‐Metal Films/H+‐Conducting Solid‐Polymer Electrolyte Assemblies: The Nitrate‐Reduction Activity in an Asymmetric Sandwich‐Type Reactor

“…Several studies have reported the lowering of the ɛ d value of Pt to a moderate value upon incorporation of Pd in the Pt catalyst . Our experimental observations for the NNR rate enhancement using binary and ternary catalyst assemblies indicate that moderate ɛ d values are obtained for the catalytic assemblies molded with equal amounts of Pt and Pd (Pt/Pd ratio ≈1).…”

Homogeneous Decoration of Au Nanoparticles on ZIF-Derived Porous CoS2 Nanocages for Nonenzymatic Hydrogen Peroxide Sensing

“…2,3 For example, aggregated Pt-Pd nanoparticles on Nafion membrane was reported for impulsive decomposition of H 2 O 2 . 4 Li 5 employed carbon-doping molybdenum carbide (β-Mo 2 C/C) to modify glassy carbon electrode, and the synergistic effect of β-Mo 2 C/C made the sensor show outstanding electrocatalytic performances toward H 2 O 2 . Ahammad 6 fabricated palladium thin film on indium tin oxide electrode for electrochemical detection of H 2 O 2 and proposed a possible reduction reaction mechanism.…”
