Publication number: 20120111801Abstract: Disclosed is a near-field photocatalyst using a ZnO (ZnO) nanowire. The photocatalyst is advantageous in that low-priced zinc is used instead of titanium, conventionally used as a photocatalyst to reduce expenses, and that it is possible to obtain overvoltage which is sufficient to generate hydrogen using an optical near field formed around an end of a ZnO nanowire without the application of additional external voltage, thus the use of a costly electrode, such as platinum, is avoided and a process is simplified.Type: ApplicationFiled: August 31, 2005Publication date: May 10, 2012Applicants: Seoul National University R & DB Foundation, POSTECH FOUNDATIONInventors: Gyu-chul Yi, Motoichi Ohtsu, Takashi Yatsui

Publication number: 20120107188Abstract: Disclosed is an exhaust gas purifying catalyst in which grain growth of a noble metal particle supported on a support is suppressed. Also, disclosed is a production process of an exhaust gas purifying catalyst, by which the above exhaust gas purifying catalyst can be produced. The exhaust gas purifying catalyst comprises a crystalline metal oxide support and a noble metal particle supported on the support, wherein the noble metal particle is epitaxially grown on the support, and wherein the noble metal particle is dispersed and supported on the outer and inner surfaces of the support. The process for producing an exhaust gas purifying catalyst comprises masking, in a solution, at least a part of the surface of a crystalline metal oxide support by a masking agent, introducing the support into a noble metal-containing solution containing a noble metal, and drying and firing the support and the noble metal-containing solution to support the noble metal on the support.Type: ApplicationFiled: July 9, 2010Publication date: May 3, 2012Inventors: Masao Watanabe, Oji Kuno, Nobusuke Kabashima, Keisuke Kishita, Noboru Otake, Hiromochi Tanaka

Publication number: 20120097522Abstract: A simple, room-temperature method of producing zinc oxide nanoparticles was established by reacting zinc nitrate hexahydrate and cyclohexylamine (CHA) in either aqueous or EtOHic medium. Particles of polyhedra morphology were obtained for zinc oxide, prepared in EtOH (ZnOE), while an irregular spherical morphology, mixed with some chunky particles forzinc oxide prepared in water (ZnOW). The results indicate that there are significant morphological differences between ZnOE and ZnOW. ZnOE showed a regular polyhedral shape, while spherical and chunky particles were observed for ZnOW. The morphology was crucial in enhancing the cyanide ion photocatalytic degradation efficiency of ZnOE by a factor of 1.5 in comparison to the efficiency of ZnOW at equivalent loading of 0.02 ZnO nanoparticles wt %. Increasing the loading wt % of ZnOE from 0.01 to 0.07 led to an increase in the photocatalytic degradation efficiency from 67% to 90% after 45 minutes and a doubling of the first-order rate constant (k).Type: ApplicationFiled: January 1, 2012Publication date: April 26, 2012Applicant: King Abdulaziz City for Science and Technology(KACST)Inventors: Abdulaziz A.
