Introduction

Yun Wang is a notable inventor based in Chengdu, China. He has made significant contributions to the field of ozone purification technology, holding 2 patents that showcase his innovative approaches to environmental solutions.

Latest Patents

One of his latest patents is focused on an ozone purification catalyst and its preparation method. This invention provides a catalyst coating that utilizes macroporous, high specific surface area materials, specifically 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, drying, calcining, and solidifying to produce the ozone purification catalyst. This catalyst demonstrates rapid and efficient ozone purification, with a wide range of complete conversion temperatures. Its excellent texture performance, high specific surface area, and large pore volume make it particularly effective for ozone purification in high-speed automotive applications. The catalyst can be tailored in terms of particle sizes and colors to meet various requirements, and it can be applied in public areas such as urban bus stations and roadside structures.

Another significant patent by Yun Wang involves a cerium-zirconium-aluminum-based composite material and a cGPF catalyst. This invention employs a stepwise precipitation method to prepare the composite material, which is then coprecipitated with zirconium and cerium sol, followed by high-temperature roasting. 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. This advancement is crucial for the large-scale application of cGPF catalysts.
