Carbon-Based Ozone Catalysts: A Green and Efficient New Choice for Environmental Protection

As environmental requirements become increasingly strict today, carbon-based ozone catalysts, with their unique performance advantages, are becoming a key technology for treating refractory organic pollutants. The carbon-based ozone catalyst developed by SINOKLE provides an efficient and reliable solution for industrial wastewater treatment through innovative material design and preparation processes.

Material properties and core technology
The carbon-based ozone catalyst uses activated carbon as the substrate, selecting high-quality raw materials with an iodine value above 1100 and a specific surface area of 1400 m²/g. Its well-developed pore structure provides ample active sites for catalytic reactions, while its abundant surface functional groups enhance catalytic activity.

SINOKLE introduces transition metal atoms into the carbon skeleton through multi-metal hetero-atom co-doping technology, significantly improving catalytic performance. Taking the cobalt-nickel dual-atom catalyst as an example, precise control of the metal ratio achieves a synergistic catalytic effect that greatly boosts ozone oxidation efficiency.

Process innovation and performance advantages
Pore-forming innovation: SINOKLE adopts three innovative pore-forming technologies: a single-impregnation multi-sintering process, water-soluble pore-forming agent addition, and the sacrificial template metal pore-forming method. These technologies ensure the catalyst maintains a high specific surface area while offering excellent mechanical strength.
Enhanced stability: through metal-nitrogen coordination bond strengthening technology, the thermal and chemical stability of the carbon-based ozone catalyst is significantly improved. The introduction of nitrogen atoms effectively anchors the metal atoms, preventing migration and aggregation and extending catalyst service life.

Practical application results

Oily wastewater treatment: in a petrochemical project in Karamay, carbon-based ozone catalyst demonstrated remarkable performance in treating oily wastewater. Influent COD of 180 mg/L was reduced to 23 mg/L, a removal rate of over 90%; oil content dropped from 35 ppm to 2.3 ppm, and indicators such as phenols and cyanide also improved substantially.
Landfill leachate treatment: SINOKLE's CDOFpatented technology adopts carbon-based ozone catalyst to treat landfill leachate with a COD removal rate exceeding 80%. In an application at a landfill in Taizhou, influent COD of about 1500 mg/L was reduced to below 200 mg/L after 40 minutes of treatment, and the B/C ratio rose from 0.22 to 0.37.
Dye wastewater decolorization: for dye wastewater with complex compositions, carbon-based ozone catalyst demonstrates outstanding decolorization capability. When treating mixed dye wastewater, chromaticity dropped from >10000 to nearly colorless, with a decolorization rate exceeding 99.9% and a mineralization rate above 45%.
