Reaction of Hydrogen with Oxygen Adsorbed on a Platinum Catalyst.
The release of hydrogen atoms by a platinum surface in contact with molecular hydrogen occurs if there is oxygen in the system. In particular, it is sufficient that the oxygen be adsorbed at the surface of the metal.
متن کاملA Combined “Electrochemical–Frustrated Lewis Pair” Approach to Hydrogen Activation: Surface Catalytic Effects at Platinum Electrodes
Herein, we extend our "combined electrochemical-frustrated Lewis pair" approach to include Pt electrode surfaces for the first time. We found that the voltammetric response of an electrochemical-frustrated Lewis pair (FLP) system involving the B(C6 F5 )3 /[HB(C6 F5 )3 ]- redox couple exhibits a strong surface electrocatalytic effect at Pt electrodes. Using a combination of kinetic competition s...
متن کاملThe Reaction between Hydrogen and Oxygen on Platinum PROGRESS IN ESTABLISHING KINETICS AND MECHANISMS
Nothing certain is understood concerning the mechanism of what is the oldest known, and the simplest, catalytic oxidation. Recent work in the Johnson Matthey Research Laboratories has partly explained some of the inconsistencies found in previous work, and has established the best conditions for studying the kinetics of this reaction. In this article new suggestions are put forward on possible ...
متن کاملHydrogen peroxide electrochemistry on platinum: towards understanding the oxygen reduction reaction mechanism.
Understanding the hydrogen peroxide electrochemistry on platinum can provide information about the oxygen reduction reaction mechanism, whether H(2)O(2) participates as an intermediate or not. The H(2)O(2) oxidation and reduction reaction on polycrystalline platinum is a diffusion-limited reaction in 0.1 M HClO(4). The applied potential determines the Pt surface state, which is then decisive fo...
متن کاملElectrodeposition of platinum nanoparticles on reduced graphene oxide as an efficient catalyst for oxygen reduction reaction
Reduced graphene oxide film was synthesized on a glassy carbon electrode by electro reduction of graphene oxide powders in aqueous solution. Then platinum nano particles were deposited on reduced graphene oxide film that was deposited on the glassy carbon electrode via electro reduction of platinum salt. The Physical morphology of the platinum on reduced graphene oxide film was evaluated by sca...
