Electrochemical behaviour of gamma hydroxybutyric acid at a platinum electrode in acidic medium [PDF]

, 2013
The electrooxidation of Gamma Hydroxybutyric Acid (GHB) on a polycrystalline platinum electrode is studied by cyclic voltammetry in acidic medium. Two oxidation peaks, A and B, are obtained in the positive scan within the potential range of the double ...

Electrooxidation of Methanol, Ethanol and 1-Propanol on Pd Electrode in Alkaline Medium

International Journal of Electrochemical Science, 2009
Here, the oxidation activity of ethanol and 1-propanol compared methanol on Pd electrode has been studied in alkaline medium. We have used the amount of coulombs (coulometry) and apparent activation energy (Ea) to measure the activity of alcohol ...

A combined "electrochemical-frustrated Lewis pair" approach to hydrogen activation: surface catalytic effects at platinum electrodes [PDF]

, 2014
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(C6F5)3 ...

Solar‐Driven Ammonia Synthesis From Nitrate Reduction Paired With CO2 Capture for Sustainable Agriculture via a Robust CuPd Heterojunction

Angewandte Chemie, EarlyView.
Laser‐assisted synthesis of CuPd amorphous/crystalline heterojunction demonstrates >80% Faradaic efficiency for nitrate‐to‐ammonia electroreduction across wide potential windows. The integrated solar‐powered electrolyzer achieves 6% solar‐to‐ammonia energy efficiency at 0.4 sun, 6–20 mg h−1 CO2 capture rate, and stability exceeding 100 h.
