Nanolithographic Fabrication and Heterogeneous Reaction Studies of Two-Dimensional Platinum Model Catalyst Systems Creator/Author :Contreras, A.M. Publication Date :2006 May 20 Resource Type :Thesis/Dissertation Research Org Ernest Orlando Lawrence Berkeley NationalLaboratory, Berkeley, CA (US) Sponsoring Org USDOE Director. Office of Science. Office of Basic EnergySciences Subject 37 INORGANIC, ORGANIC, PHYSICAL AND ANALYTICAL CHEMISTRY; CATALYSTS; ELECTRON BEAMS; FABRICATION; PLATINUM Description/Abstract : In order to better understand the fundamental components that govern catalytic activity, two-dimensional model platinum nanocatalyst arrays have been designed and fabricated. These catalysts arrays are meant to model the interplay of the metal and support important to industrial heterogeneous catalytic reactions. Photolithography and sub-lithographic techniques such as electron beam lithography, size reduction lithography and nanoimprint lithography have been employed to create these platinum nanoarrays. Both in-situ and ex-situ surface science techniques and catalytic reaction measurements were used to correlate the structural parameters of the system to catalytic activity. http://www.osti.gov/bridge/servlets/purl/886081-PFlKHc/ |
