Influence of the Cathode Platinum Loading and of the Implementation of Membranes on the Performance of Air-Breathing Microbial Fuel Cells

Mateo, Sara; Fernandez-Morales, Francisco; Cañizares, Pablo; Rodrigo, Manuel

2017 Electrocatalysis

doi:10.1007/s12678-017-0393-7

The use of catalysts and membranes in microbial fuel cells (MFCs) is rather controversial. Platinum is the best catalyst to improve the oxygen reduction reaction and the implementation of an ion exchange membrane may help to avoid the oxygen leakages from the cathode to the anode compartments...

The Selective Electrochemical Detection of Dopamine Using a Sulfated β-Cyclodextrin Carbon Paste Electrode

Gnahore, Gama; Velasco-Torrijos, Trinidad; Colleran, John

2017 Electrocatalysis

doi:10.1007/s12678-017-0402-x

The present work describes a novel approach for the determination of dopamine (DA) using carbon paste electrodes modified with sulfated β-cyclodextrin (S-β-CDCPE). The electrodes show high affinity towards DA electrochemical oxidation. DA returned a concentration detection range 5 × 10−7 M to 5 ×...
