Latest Patents
One of Yun Li's latest patents is the "Ozone purification catalyst and preparation method and application thereof." This invention provides a catalyst coating that utilizes macroporous, high specific surface area, and CeO and/or LaO modified AlO as the carrier material, with Mn and/or Pd as the active components. The preparation method involves creating an AlO-based material through a sol-gel process, followed by loading the active components onto the carrier material. The resulting ozone purification catalyst demonstrates rapid and efficient ozone purification, with a wide range of complete conversion temperatures. The catalyst's excellent texture performance, high specific surface area, and large pore volume make it particularly effective for use in high-speed vehicles. Additionally, the catalyst can be applied in various public areas, such as urban bus stations and roadside structures.
Another notable patent is the "Cerium-zirconium-aluminum-based composite material, cGPF catalyst and preparation method thereof." This invention employs a stepwise precipitation method to create a cerium-zirconium-aluminum-based composite material. The process involves preparing an aluminum-based pre-treated material, coprecipitating it with zirconium and cerium sol, and roasting it at high temperatures. The resulting composite material exhibits improved compactness and density, which enhances the performance of the cGPF catalyst by reducing back pressure and improving ash accumulation resistance.
