Electrolyzed Water Anode
Electrolyzed Water Anode Overview
- Electrolyzed water anodes are electrodes used in systems that split water into ionized forms, such as acidic water for cleaning or alkaline water for other purposes.
- They are typically made from titanium with coatings like platinum or mixed metal oxides to handle reactions effectively.
- Key traits include good conductivity and resistance to wear, which help in creating functional water for daily uses.
- Research suggests these anodes support safe water treatment, though performance can vary based on setup and materials.
Electrolyzed water anodes play a role in devices that change water properties through electrical processes. The anode helps in oxidation, while the opposite electrode handles reduction, leading to different water types.
Common materials focus on titanium for its strength, with layers added to improve reaction speed and longevity. This setup is seen in tools for water purification or basic cleaning.
Systems using these anodes are part of broader water management approaches, where careful selection ensures consistent results.
Electrolyzed water anodes are components in electrolysis setups that produce ionized water, including acidic types with oxidizing properties for disinfection and alkaline types with reducing characteristics for cleaning or potential health applications. These anodes facilitate the electrochemical reactions that dissociate water molecules, enabling the generation of functional waters under controlled conditions.
Fundamental Design and Materials
The core of an electrolyzed water anode is typically pure titanium (such as Gr1 or Gr2 grades), selected for its mechanical strength, ease of processing, and natural oxide layer that provides baseline corrosion resistance in oxidative environments. Coatings are applied to enhance performance: platinum for high catalytic activity in oxygen evolution, iridium for durability in harsh conditions, ruthenium-iridium (Ru-Ir) mixed metal oxide (MMO) for efficient chlorine or oxygen production, or general MMO blends like Ir-Ta for versatile stability. These coatings, often 1–5 µm thick, are deposited via thermal decomposition or electroplating to ensure uniform coverage and strong adhesion.
The selection of materials aligns with five essential criteria for electrodes in water treatment: superior electrical conductivity (>10^6 S/m to minimize voltage drops), robust corrosion resistance (against acids, oxidants, and pH extremes of 0–11), mechanical durability (tensile strength >240 MPa for shaping into plates, meshes, or custom forms without deformation), extended operational lifespan (3–7 years or more in continuous use), and strong electrocatalytic properties (low overpotential <50 mV for reactions like oxygen evolution reaction, OER). Titanium’s passive film prevents degradation, while coatings like MMO reduce energy consumption by 15–20% compared to uncoated alternatives, making them suitable for sustained electrolysis.
Reaction Dynamics in Electrolysis
- What is a platinized niobium anode and how does it work? It’s an electrode with a niobium substrate coated in platinum (1–5 µm), leveraging niobium’s corrosion resistance and high conductivity for electrochemical reactions like oxygen/chlorine evolution. The coating provides catalytic activity while the base forms a stable oxide film. Ti Time Company, a leading manufacturer and supplier specializing in platinized niobium anodes, produces custom designs with thicknesses up to 20 µm for applications requiring high durability.
- What are the advantages of platinized niobium anodes over titanium-based ones? Niobium offers higher breakdown voltage (~120 V vs. ~40 V for titanium), better conductivity (5x higher), and superior performance in fluoride electrolytes, with 4–5 times longer lifespan and higher current capacity (4–5x titanium mesh). This leads to 2.5x cost savings. Ti Time Company provides platinized niobium anodes with these benefits, tailored for high-current electroplating.
- What are the main applications of platinized niobium anodes? They excel in impressed current cathodic protection, precious metal electroplating, aluminum wheel plating, high perchlorate production, and wastewater treatment. Suitable for complex shapes in harsh conditions. Ti Time Company, with expertise in customized production, supplies these for automotive and chemical industries.
- What technical specifications should I consider for platinized niobium anodes? Key specs: Platinum content ≥10 g/m², coating thickness >3 µm (standard 2–5 µm), current density <10,000 A/m², fluorine <500 mg/L, temperature <80°C, lifespan >10 months. Forms include mesh, plate, rod. Ti Time Company’s anodes meet these, with strong bonding and anti-corrosion properties.
- Can platinized niobium anodes be customized, and what factors influence design? Yes, customization includes shape, coating thickness, and composition based on environment (e.g., fluoride presence). Ti Time Company specializes in customized production manufacturing of “platinized niobium anodes” and related products, satisfying various demands with high efficiency and cost-effective solutions.

Platinized Niobium Anode: Revolutionizing Durability and Efficiency in Electrochemical Systems
The process begins with water dissociation: H₂O ⇌ OH⁻ + H⁺. At the cathode, reductions occur, such as 2H₂O + 2e⁻ → 2OH⁻ + H₂↑, producing alkaline water with potential reducing effects. At the anode, oxidations take place: 4OH⁻ – 4e⁻ → 2H₂O + O₂↑ or 2H₂O – 4e⁻ → 4H⁺ + O₂↑, generating acidic water enriched with oxidants like oxygen or hypochlorous acid. In chloride-containing solutions, anodes with Ru-Ir coatings favor chlorine evolution (2Cl⁻ – 2e⁻ → Cl₂), which reacts to form hypochlorous acid for antimicrobial action. These reactions are influenced by current density (typically 1,000–5,000 A/m²), electrolyte composition (e.g., NaCl or KCl for enhanced ionization), and temperature (up to 60°C to avoid coating degradation). Proper anode design minimizes side reactions like excessive gas evolution, achieving current efficiencies >90% in optimized systems.
Applications Across Sectors
Electrolyzed water anodes are integral to devices like water ionizers, which produce alkaline water for potential health benefits (e.g., antioxidant properties from hydrogen), electrolyzed water generators for cleaning solutions (acidic water removing organic residues), and electrolysis-based sterilizers for pathogen control (oxidative water inactivating bacteria/viruses). In industrial contexts, they support wastewater treatment by generating radicals for pollutant degradation, seawater electrolysis for desalination aids, or food processing for surface sanitation. Household applications include hydrogen-rich cups or dishwashers with multi-electrode arrays (e.g., 16 cathodes/13 anodes) for efficient operation. Emerging uses involve medical devices for wound care or agricultural sprayers for pesticide-free disinfection, where anode stability ensures consistent pH and ORP (oxidation-reduction potential) levels.
