Latest Patents

Ji-Man Kim holds a patent for a novel titania photocatalyst and its preparation method. This invention relates to a unique titania photocatalyst that is prepared through a series of specific steps. The process involves encapsulating titanium tetraisopropoxide in zeolite support by adding citric acid to isopropyl alcohol. Ethylene glycol is then dissolved to create a uniformly dispersed mixture solution, which is encapsulated in zeolite cavities. The advantages of this titania photocatalyst include a greatly increased surface area and photocatalytic activity due to its smaller granule size compared to commercial titania powder. Additionally, it is uniformly dispersed within quantum-sized zeolite cavities, preventing the formation of large clusters that are common with conventional titania hyperfine powder. This innovation maximizes the quantum efficiency of titania powder in the UV region, effectively removing hazardous gases like ammonia and sulfide from the atmosphere and organic materials from wastewater through photo-oxidation reactions.
