After introducing the fabrication processes and properties of boron doped diamond, we will introduce mechanism of electrochemical oxidation of water on boron doped diamond electrode, in this section, we will find out how boron doped diamond electrode accomplishes efficient water remediations through electrochemical advanced oxidation processes.
Boron doped diamond electrodes excels in electrochemical generation of oxidizing agents such as hydroxyl radicals.
Boron-doped diamond electrode performed much better oxygen hydrogen evolution than conventional electrode materials, which eventually increase electrochemical generation of various oxidizing agents such as hydroxyl radicals, Ozone and hydrogen peroxide. As a polar molecule, water exhibits a positive and negative end. During the process of water electrolysis, the positively charged hydrogen atoms are attracted to the negatively charged electrode (cathode), while the negatively charged oxygen atom is drawn towards the positively charged electrode (anode). As a result, the water molecules dissociate into their respective ions: hydrogen ions (H+) at the cathode and hydroxide ions (OH-) at the anode.

Hydroxyl radical is one of most active oxidizing agents, and it presents non-selective mineralization toward oxidizable molecules for its high electrochemical oxidation potential,check the oxidation potential of oxidizing agents generate from the solution(electrolyte, or when it comes to was. Hydroxyl radicals could decompose organic compounds with no concentration, hydroxyl radicals mineralize the vast majority of organic pollutants, especially bio-recalcitrant organic compounds such as antibiotics, steroids, BTEX, PCBs, PAHs, APIs, etc. It’s an eco oxidizing agents, as hydroxyl radicals naturally decompose into water and oxygen, without leaving behind any harmful materials.
Hydroxyl radicals mineralization of organic compounds
The water electrolysis process can be summarized by the following half-reactions:
At the cathode: 2H+ + 2e- -> H2 (hydrogen gas)
At the anode: O2 + 2H2O + 4e- -> 4OH- (oxygen gas) Discharge of water molecules lead to hydroxyl radicals formation. Hydroxyl radicals decompose organic compounds in fundamental mechanisms: addition of radicals, abstraction of hydrogen, electron transfer, and radical combination.
