Sb–SnO₂ Coated Titanium Electrode

Sb–SnO₂ Coated Titanium Electrode | DSA Anode | FrankLab

Antimony-Doped Tin Oxide Coating · High Oxygen Evolution Potential · Ideal for Electrochemical Oxidation, AOPs & Wastewater Treatment

Product Overview

The FrankLab Sb–SnO₂ Coated Titanium Electrode is a high-performance DSA (Dimensionally Stable Anode) composed of:

•Titanium substrate (Grade 1 or Grade 2)

•Antimony-doped SnO₂ (Sb–SnO₂) catalytic coating

Sb–SnO₂ is one of the most widely used coatings for electrochemical advanced oxidation processes (EAOPs) because it offers:

•Extremely high OER overpotential

•Strong oxidation ability for organic contaminants

•Excellent stability in acidic and neutral media

•Lower cost compared with noble-metal MMO coatings

This electrode is especially suitable for:

•Electrochemical degradation of dyes, pharmaceuticals, PFAS, antibiotics

•Advanced oxidation (AOP) systems

•Wastewater mineralization

•Electrochemical oxidation (EO) reactors

•Disinfection and electrochemical treatment

•Laboratory and pilot-scale environmental research

Key Features

• High Oxygen Evolution Potential (OEP)

The Sb–SnO₂ coating has one of the highest OER potentials among DSA electrodes:

•Enables selective oxidation of organics without excessive oxygen evolution

•Allows strong mineralization capability in EAOP systems

•Reduces unwanted side reactions

• Strong Oxidation Capability

Ideal for degrading:

•Organic dyes

•Pharmaceutical pollutants

•Pesticides

•Phenols & aromatic compounds

•COD reduction

•Complex industrial wastewater

• Chemically Robust Titanium Substrate

•Lightweight

•Corrosion resistant

•Long-term mechanical stability

•Excellent adhesion with oxide layers

• Cost-Effective Compared to Noble-Metal Anodes

A practical alternative to:

•Boron-doped diamond (BDD)

•Ir–Ta MMO

•Ru–Ir MMO

while maintaining strong oxidative performance.

• Stable Electrochemical Behavior

•Suitable for CV, LSV, EIS

•Low degradation rate during long-term oxidation

•Supports high current density
