After introducing the synthesis and fabrication processes and properties of boron-doped diamond electrode, 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.

As a polar molecule, water exhibits a positive and negative end. During the water electrolysis processes, 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.

Boron doped diamond electrodes excels in electrochemical generation of active oxygen species, mainly hydroxyl radicals.
