Anion exchange membrane fuel cells (AEMFC) are a promising technology to allow the application of non-precious metal catalysts. While many such catalysts have been identified in numerous recent fundamental research studies, reports evaluating these realistic AEMFC catalyst layers together with stability assessments rare. In present work we show that fast and reliable evaluation optimization Fe-N-C-based oxygen reduction reaction (ORR) can be achieved using gas diffusion electrode (GDE)...
Abstract Electrochemical decarboxylation of carboxylic acids is considered a sustainable method to improve the quality pyrolysis oil. In this study, we assess effect monovalent alkali cations (of acetates) on performance Pt electrodes in acid and competing OER, using various electrochemical methods. We reveal strong cation dependence generally following trend Li + <Na <K ~Cs within large pH range. Using rotating ring disc electrode measurements, highlight contribution oxygen evolution...
Tuning the surface of boron-doped diamond functionalised with platinum nanoparticles and thin films alters selectivity hydroxyl-radical-mediated indirect electrooxidation acetic acid to Kolbe product.
Platinum is commonly applied as the anode material for Kolbe electrolysis of carboxylic acids thanks to its superior performance. Literature claims that formation a barrier layer on Pt in acid electrolyte suppresses competing oxygen evolution and promotes anodic decarboxylation. In this work, we show by using combination complementary in-situ ex-situ surface sensitive techniques, presence acetate ions also prevents passive oxide platinum at high potentials. Furthermore, dissolves actively...
The decarboxylation (of mixtures) of short-chain carboxylic acids (C2 and C3) on oxidised platinum anodes was investigated using constant current galvanic square-wave pulse electrolysis. At current, a high...

Dylan G. Boucher opened the discussion of paper by Talal Ashraf: What does surface termination look like after electrolysis? BDD chemistry can change quite substantially during process. Ashraf responded: Since we are using boron-doped diamond with a high concentration boron (2000–5000

Carboxylic acids, a major fraction of pyrolysis oil can be transformed electrochemically in alkanes and alcohols by Kolbe Hofer Moest reaction. The selectivity electrochemical decarboxylation depends on various factors, i.e. electrode material reaction conditions (supporting electrolyte, pH current densities) which are well explained the literature 1–3 . Alkali metal cations (Li + , Na K Cs ) widely considered inert, 4 nevertheless recent studies, significant influence different reactions...
