The Science Behind
BDD Electrochemistry
Understanding how boron-doped diamond electrodes deliver superior performance in oxidation, disinfection, and thermal management.
What is BDD?
BDD stands for Boron-Doped Diamond — a synthetic diamond film where boron atoms are incorporated into the diamond crystal lattice during the chemical vapor deposition (CVD) growth process.
This doping transforms diamond from an electrical insulator into a conductive material with extraordinary electrochemical properties. BDD electrodes exhibit the widest electrochemically active potential window of any known electrode material, making them exceptionally powerful for generating oxidizing species.
The result is an electrode that can produce hydroxyl radicals (OH) — among the most powerful oxidizing agents in nature — directly from water molecules at its surface, enabling pollutant destruction without adding chemicals.

How It Works
From electrode fabrication to clean output in four steps.
BDD Electrode Fabrication
Boron-doped diamond films are synthesized on substrate materials using chemical vapor deposition (CVD) technology.
Electrochemical Activation
When voltage is applied, the BDD electrode surface generates hydroxyl radicals (OH) — one of the strongest oxidizing agents known.
Pollutant Degradation
The generated radicals attack and break down organic contaminants into harmless byproducts (CO2 and H2O) without secondary pollution.
Clean Output
Treated water or disinfected space meets regulatory standards with minimal environmental impact.
