Lead Dioxide Titanium Anode Manufacturer
Factory-direct PbO₂/Ti anodes engineered for high oxygen evolution potential, powerful oxidation, aggressive wastewater treatment, electrowinning, hydrometallurgy, electroplating, and harsh acidic electrochemical systems.
High Oxygen Evolution Potential for Harsh Oxidation Systems
When ordinary anodes cannot oxidize persistent pollutants efficiently, PbO₂/Ti provides stronger anodic oxidation power.
PbO₂/Ti anodes are engineered for processes that require high anodic potential and strong oxidative capability. Their high oxygen evolution potential helps direct more electrochemical energy toward target oxidation reactions instead of wasting it on early oxygen evolution.
Hele Titanium manufactures titanium-based lead dioxide anodes with controlled substrate preparation, protective intermediate layers, electrodeposited PbO₂ coating, and strict SEM / XRF / adhesion verification. These anodes are designed for high-COD wastewater, dye degradation, phenol treatment, hydrometallurgy, electrowinning, electrochemical synthesis, and other aggressive oxidation processes.

When Should You Choose PbO₂/Ti Lead Dioxide Anodes?
PbO₂/Ti anodes are selected when high oxygen evolution potential, strong oxidation capability, acid durability, and cost-effective large-scale operation are more important than high-purity inert behavior or reaction-specific MMO selectivity.
Best for Strong Oxidation
PbO₂/Ti anodes provide high oxygen evolution potential, making them suitable for advanced oxidation of difficult organic pollutants and aggressive industrial effluents.
- • High-COD wastewater
- • Dye & Phenol degradation
- • Landfill leachate
- • Persulfate synthesis
Different from MMO & Pt/Ti
MMO anodes are reaction-specific. Pt/Ti is ideal for high-purity precision. PbO₂/Ti is chosen when strong oxidation power and cost-effective high-OEP performance are required.
- • PbO₂/Ti: High-OEP oxidation
- • Ru-Ir MMO: Chlorine evolution
- • IrO₂ MMO: Durable OER
- • Pt/Ti: High-purity inert apps
Built Around Layer Integrity
Performance depends on substrate activation, intermediate layer quality, β-PbO₂ coating density, current density, temperature, and handling discipline.
- • Intermediate layer protection
- • β-PbO₂ crystalline structure
- • Current density control
- • Fluoride risk management

1. What Is a Lead Dioxide Titanium Anode?
A brief overview of the fundamental composition and function of PbO₂/Ti anodes in electrochemical applications.
A PbO₂/Ti anode is a dimensionally stable anode consisting of a titanium substrate coated with a functional lead dioxide layer. The titanium provides mechanical strength and dimensional stability, while the PbO₂ coating provides high oxygen evolution potential and strong oxidation capability.
2. Why High Oxygen Evolution Potential Matters
Understanding how high OEP improves energy efficiency and targets specific oxidation reactions.
High OEP helps suppress premature oxygen evolution. In aqueous solutions, applying current often splits water into oxygen gas. If the anode has a low OEP, energy is wasted making bubbles. A high-OEP anode like PbO₂ forces the electrical energy to drive target oxidation reactions, such as destroying difficult organic pollutants or generating strong oxidants.
