Q2. what is the chemistry of a boron-doped diamond?
Electrochemical oxidation of 3- methylpyridine at a boron-doped diamond electrode: application to electroorganic synthesis and wastewater treatment.
Q3. What was the effect of the oxidation of organics on the cell voltage?
Despite being doped with boron (or less frequently with nitrogen or fluoride), the conductivity of diamond electrodes is much lower than that of other typical electrodes used in electrolysis and hence the cell voltage and the ohmic loses are greater.
Q4. What is the main point of interest in electrochemical technology?
For several years, platinum and graphite carbon-based electrodes focused the interest, as a consequence of their wide use in other electrochemical applications, even as different as electro-analysis.
Q5. What is the role of the cathode in the EAOP?
the type of cathode plays a very important role, not only the material but also the mechanical design and GDE (gas diffusion electrode) becomes a very important choice will allows to obtain very high efficiencies.
Q6. What was the first evidence of the formation of polymers on the surface of the electrodes?
For the second, the formation of polymers on the surface of the electrodes, which in turn produces a sort of passivationwas a clear indicator and prevented the efficient use of the technology (Iniesta et al., 2001).
Q7. What does the scale up study mean?
This means that a great amount of work has to be done in order to face this important problem and for this reason, and also because of the mass transfer limitations, the cell design is taking a big importance nowadays, trying to improve throughout electrochemical engineering what it could not be improved with the material itself with special mechanical designs that try to minimize the interelectrodic gap, maximize the turbulence with promoters, reduce the ohmic loses with special current feeders, etc.(Souza et al., 2016) Likewise, scale-up has not always been faced in the right way, sometimes because of the economic difficulties and sometimes because the lab-scale is still ill defined and hence scale up studies are not worth.
Q8. What is the role of hydroxyl radicals in the oxidation of organics?
In addition, despite oxidation of water to oxygen could be explained through the formation of hydroxyl radicals, there were no evidences of the role of these hydroxyl radicals in the oxidation of organics.
