In this work, different experimental parameters influencing the straightforward nanoparticles synthesis method, so-called Bromide Anion Exchange (BAE) were scrutinized. It was found that a bromide ion to metal(s) molar ratio of 1.5 gave the best electrochemical activity of the obtained catalysts toward the organics oxidation. The revisited BAE synthesis approach allows the preparation of highly active AuPt/C and AuPd/C nanomaterials. It has been highlighted that this method changes drastically the structure of AuPd nanostructures leading to alloyed system when Au atomic content is higher than 50%. These goldbased materials can be considered as advanced surfactant-free nanoparticles for anode electrodes design in abiotic or hybrid glucose biofuel cell. Furthermore, qualitative and quantitative analyses of glycerol conversion indicate that glycolate and glycerate are the main final products with selectivity higher than 40 and 30%, respectively
