ZV-805 Ozone Oxidation Catalyst

Introduction

ZV-805 Ozone Oxidation Catalyst is the latest high-efficiency iron-based catalyst. This catalyst employs a porous, highly active nano-silica-calcium-alumina composite oxide as its carrier. It incorporates nano-iron oxide active components, pseudo-boehmite, novel polyhydroxy nano-iron oxide, and sesbania powder through an efficient coordination combination preparation method. This precisely regulates the synergistic interaction between the carrier's acidic sites and oxidative active sites, addressing the challenges of low catalytic activity and poor structural stability inherent in traditional iron-based ozone oxidation catalysts. Simultaneously, under oxygen-enriched high-temperature calcination and sintering, the incorporation of hydrophilicity enhancers significantly enhances catalyst strength, resolves active component detachment issues, and ensures extended catalyst service life.

Technical Principles and Characteristics

The technical principle of ozone catalytic oxidation involves the generation of highly reactive free radicals with strong oxidizing capabilities under the influence of a catalyst. These radicals break the double bonds in organic molecules, oxidizing large-molecule organic pollutants into smaller organic compounds, which are then converted into carbon dioxide and water. This process enables the treatment of organic pollutants in wastewater at ambient temperature and pressure, effectively reducing the wastewater's BOD/COD ratio.
For ozone catalytic oxidation technology, catalyst selection is critical to achieving high-efficiency oxidation. Based on extensive experimental and engineering applications, our company has developed the ZV-805 catalyst with outstanding catalytic performance by utilizing advanced catalytic materials and efficient preparation techniques. 

This catalyst features:
1) High catalytic activity: A novel polyhydroxy nano-iron oxide material serves as the active component. It exhibits strong synergistic effects with the porous structure and composite oxide carrier while enhancing the dispersion of active sites. This promotes ozone decomposition efficiency, boosts pollutant degradation capacity, and reduces ozone dosage requirements.
2) Extended service life: Professional high-temperature calcination and sintering techniques, combined with the addition of hydrophilic enhancers, significantly improve the catalyst's wear resistance and compressive strength. This ensures robust bonding between the active component and the carrier, preventing detachment during operation.
3) Environmental friendliness: Free from heavy metal contaminants, the catalyst can be recycled and reused after reaching its service life, eliminating waste discharge.
