Latest Patents
Fangxia Feng's latest patent focuses on a ceria-based mixed-metal oxide structure, which serves as a catalyst support, co-catalyst, and getter. This innovative material boasts a large surface area per weight, typically exceeding 150 m/g. The structure consists of nanocrystallites with diameters of less than 4 nm, and it includes pores larger than the nanocrystallites, ranging from 4 to about 9 nm. The ratio of pore volumes to skeletal structure volumes is typically less than about 2.5, while the surface area per unit volume of the oxide material exceeds 320 m/cm. This design minimizes internal mass transfer resistance and maximizes effective surface area for reaction activity. The mixed metal oxide is ceria-based and includes zirconium (Zr) and/or hafnium (Hf), produced through a novel co-precipitation process. A highly dispersed noble metal catalyst, such as platinum (Pt), can be loaded onto the mixed metal oxide support after a selected acid surface treatment. The careful ratioing of cerium and other metal constituents enhances the catalytic performance, with rhenium being further loaded onto the support to increase catalyst activity. This metal-loaded mixed-metal oxide catalyst is particularly effective in water gas shift reactions associated with fuel processing systems, especially for fuel cells.
