Latest Patents
Hee Seok Chai holds a patent for a novel titania photocatalyst and its preparation method. This invention involves a unique process that includes encapsulating titanium tetraisopropoxide in zeolite support with the addition of citric acid to isopropyl alcohol. The method further includes dissolving ethylene glycol to create a uniformly dispersed mixture, which is then encapsulated in zeolite cavities. The advantages of this titania photocatalyst include a significantly 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 powders. This innovation maximizes the quantum efficiency of titania powder in the UV region, allowing for effective removal of hazardous gases like ammonia and sulfide from the atmosphere, as well as organic materials from wastewater through photo-oxidation reactions.
