Carbon-based ozone catalysts have attracted much attention in the field of industrial wastewater advanced treatment in recent years, yet few high-quality products can stably operate in real engineering applications. SINOKLEKHC-F1001 (also known as KHC-PC1001) achieves performance indicators of 70% COD removal and 95% color removal thanks to three technological breakthroughs in its preparation process and a cobalt-nickel dual-atom synergistic catalytic design.

I. Three Innovative Pore-forming Processes

The pore structure of carbon-based catalysts directly determines their specific surface area and number of active sites. The SINOKLE R&D team adopted three complementary pore-forming schemes in the preparation process:

The first is a single-metal single-load multiple-sintering process. Traditional co-loading tends to cause metal agglomeration, clogging the micropores of the carbon matrix. SINOKLE's approach is"do one thing at a time" - load only one metal each time, sinter it, then load the next, which ensures uniform metal loading and maximizes the number of oxidation active sites while effectively avoiding metal agglomeration risk.

The second is a water-soluble porogen addition technique. During metal loading, addwater-soluble porogens such as PEG, PVP, and PVA; these substances are uniformly distributed during mixing and removed in subsequent drying or calcination, forming a specific pore structure in the catalyst. The advantage of this method is controllable pore size and distribution.

The third is a sacrificial-template metal pore-forming method. Using a soluble metal such as zinc as a template, the zinc evaporates during catalyst calcination and acts as a porogen, producing numerous open channels. Through the synergistic effect of these three processes,KHC-PC1001 achieves a micropore specific surface area of 1100-1150 m2/g and a mesopore specific surface area of 10-100 m2/g, with a pore structure far superior to traditional coconut-shell carbon.

II. Cobalt-Nickel Dual-Atom Synergistic Catalysis

In the design of catalytic active components, SINOKLE adopted a cobalt-nickel dual-atom synergistic strategy. Cobalt and nickel atoms form dual-atom active sites on the carbon-based carrier; through synergistic regulation of the electronic structure, the activation energy of ozone decomposition is significantly reduced. Meanwhile, multi-metal heteroatom co-doping further amplifies the catalytic effect, achievingthe '1+1>2' goal. Nitrogen-doping anchoring of metal atoms ensures long-term stability of the metal active components, avoiding loss of active components during operation.

III. Parameter Comparison with Similar Products

Compared with traditional alumina-silicate-based catalysts,KHC-F1001 shows significant advantages in specific surface area (1400 m2/g vs 200-400 m2/g), strength (95% vs usually 80%-90%), and service life (3-5 years vs usually 1-2 years). Compared with ordinary coconut-shell carbon-based catalysts, its micropore+mesopore synergistic pore structure provides a more efficient mass-transfer path and more active sites.

IV. Application Performance

Core parameters of KHC-F1001: bulk density 0.45-0.55 g/cm3, pH applicability 3-11, ozone decomposition rate 90%, COD removal 70%, color removal 95%, ozone-specific COD removal 1.1-1.5 g O3/g COD. Combined with SINOKLE'sCDOFtechnology, ozone oxidation performance can be improved by another 4x, with footprint only 10%-20% of traditional processes.

From Karamay Petrochemical to Taizhou landfill, from Inner Mongolia pharmaceuticals to a refinery in Uzbekistan,the actual engineering data of KHC-F1001 continuously validate the technical advancement of its preparation process. For wastewater treatment engineers pursuing ultimate catalytic efficiency, the process details of this product are worth in-depth study.
