New Breakthrough in Wastewater Treatment: SINOKLE's Precious-Metal Heterogeneous Catalytic Technology Explained
In today's era of rapidly advancing technology, SINOKLE, relying on strong R&D accumulation and continuous innovation practice, keeps leading the industry frontier. The company has successfully developed and obtained patent authorization for a series of precious-metal-doped heterogeneous ozone catalytic materials, which have been applied at scale in wastewater treatment in petrochemical, pharmaceutical, printing and dyeing, environmental protection and many other industries. With their efficient catalytic performance, excellent mechanical strength, huge specific surface area and outstanding acid and alkali resistance, these materials are driving innovation in wastewater treatment technology in related fields.
Heterogeneous ozone catalysts usually exist in solid form. Compared with homogeneous catalytic reaction systems, heterogeneous catalysts can be separated and recovered by simple physical methods, reducing operation steps and costs and saving wastewater treatment costs. Their active metal components are firmly anchored on the support, significantly reducing the corrosion of treatment equipment by peroxides that occurs in traditional homogeneous catalysis. Meanwhile, most of these materials have rich pore structures, which increase the contact interface with reactants, expose more active sites, and effectively promote the reaction rate.
SINOKLE's series of heterogeneous ozone catalysts takes multiple transition metal oxides as the core catalytic components, and innovatively dopes precious metals such as platinum, palladium, rhodium, silver, ruthenium, cobalt and nickel uniformly onto the material surface in specific processes and proportions. For the characteristics of different wastewater types, the ratios among the components were optimized through extensive experiments and engineering verification. The introduction of precious metals can significantly lower the activation energy of ozone catalytic reactions, accelerate the self-decomposition of ozone in the water body, and increase the generation concentration of hydroxyl radicals (OH radicals), thereby greatly enhancing ozone oxidation efficiency and utilization. Verified results show that its oxidation efficiency is 2 to 5 times higher than ozone oxidation alone.
Technical advantages:
Uses multiple transition metal oxides and precious metals as catalytic components, with excellent adaptability and high catalytic activity for different wastewater types;
Adopts catalyst loading and multi-stage precise temperature-controlled sintering technology to reduce component loss while ensuring active components and high strength, guaranteeing stable performance;
Uses highly active component materials as the catalyst support, with a special micropore forming technology achieving a high specific surface area; the supported catalyst has a good loading effect, fast catalytic reaction rate and high efficiency.
Catalytic ozone is efficiently converted to produce OH radicals, with an oxidation efficiency 2-5 times higher than traditional ozone catalytic oxidation.
Uses atomic deposition technology to modify the catalyst; the catalyst support is super hydrophilic, so the catalyst is not easily contaminated, scaled or clogged and can run for long cycles.
During catalyst preparation, special pore-forming and atomic deposition modification technologies give it super hydrophilicity, enhancing its anti-pollution and anti-clogging capabilities; multi-stage precise temperature-controlled sintering technology minimizes component loss during use and avoids secondary pollution; the material also has an extremely high specific surface area (usually over 300 m2/g), which means it provides extremely rich reactive active sites, significantly accelerating the reaction process and thus achieving higher treatment capacity and better economic benefits within limited space.
Catalyst performance parameters
At the same time, in the chemical, environmental protection and other fields, catalysts often need to face various complex environments and conditions. SINOKLE's heterogeneous ozone catalyst has outstanding acid and alkali resistance and can maintain stable catalytic performance even in strongly acidic environments. This characteristic enables it to be applied in a wider range of fields, bringing customers more choices and convenience. Currently, the heterogeneous ozone catalysts developed by SINOKLE have been widely applied in many industries and fields. Whether in chemical production, environmental governance or energy development, they have demonstrated excellent catalytic effects and outstanding performance.
