Platinum-coated titanium anodes consist of a high-purity titanium substrate (Grade 1/2) with a thin platinum layer (0.5–3 μm) applied via electroplating or physical vapor deposition. Designed for persulfate synthesis, these anodes catalyze the oxidation of sulfate ions (SO₄²⁻) to persulfate (S₂O₈²⁻) in electrolytic cells, leveraging platinum’s high electrocatalytic activity and titanium’s corrosion resistance.
Advantages:
High Catalytic Efficiency: Platinum lowers the overpotential for sulfate oxidation, enabling persulfate yields of 85–90% at current densities of 20–50 A/dm²—far exceeding graphite or MMO anodes (50–60% yield).
Corrosion Resistance: Titanium withstands aggressive acidic electrolytes (1–3 M H₂SO₄) and high temperatures (60–80°C), ensuring stable operation for 3–5 years.
Pure Product Output: Minimal metal leaching preserves persulfate purity (99.5%+), critical for applications in water treatment and chemical synthesis.
Energy Efficiency: Reduces cell voltage by 0.5–1.0 V compared to traditional anodes, cutting energy consumption by 15–25%.

production
1. Substrate treatment: it needs to be treated by roughing, cleaning and removing oil, which can increase the compactness of catalytic.
2. Brushing coating:After substrate treatment, it will be proceeded brush coated. The main coated content is platinum group metal, which is a kind of mixed solution.Then, heat treatment will be going on after drying.The whole procedure need to be repeated many times. This method is better to form thin oxide catalytic that is lamellar adhere to substrate surface.
Certification
Qixin is ISO 9001:2015 certified and own more than 10 patents. All its processes and procedures are documented and controlled in accordance with these standard. Qixin has strict product quality control procedure, from raw material to finished product, all the process is tested qualified to assure high quality product.
