Sinopec has been granted an invention patent: “Precious metal catalysts and their preparation methods and applications, as well as a method for preparing 2,5-furandicarboxylic acid.” According to data from the Tianyancha app, Sinopec (600028) has obtained a new invention patent; the title of this patent is “Precious metal catalysts and their preparation methods and applications, as well as a method for preparing 2,5-furandicarboxylic acid.” The patent application number is CN202210518731.X, and the date of grant is March 27, 2026. Patent Abstract: This invention relates to the field of chemical engineering, and discloses precious metal catalysts as well as their preparation methods and applications, as well as a method for preparing 2,5-furandicarboxylic acid. The catalyst comprises sulfur-doped nanocarbon cages and active components loaded on the sulfur-doped nanocarbon cages, the active components being selected from Ru and optionally at least one of Pt, Pd, and Au ； Sulfur-doped nanocarbon cages possess both microporous and mesoporous structures. The BET specific surface area of these sulfur-doped nanocarbon cages is greater than 500 m2/g, with the specific surface area within the micropores accounting for less than 30% of the total specific surface area ； The total pore volume of sulfur-doped nanocarbon cages is greater than 1 cm3/g, and the proportion of micropore volume to the total pore volume is less than 15% ； The X-ray photoelectron spectroscopy analysis showed that the mass percentage of carbon on the surface of the nanocarbon cages was 80–98%, while the mass percentage of sulfur was 0.1–10%. This catalyst can be used to prepare 2,5-furandicarboxylic acid without the need for basic compounds or acidification treatment.
