B3LYP calculations were carried out to study the insertion of iridium (Ir) and rhodium (Rh) clusters into a C−H bond of ethane, which is often the ratelimiting step of the catalytic cycle of oxidative dehydrogenation of ethane. Our previous research on Ir catalysis correlates the diffusivity of the lowest unoccupied molecular orbital of the Ir clusters and the relative activities of the various catalytic sites. The drawback of this research is that the molecular orbital visualization is qualitative rather than quantitative. Therefore, in this study on C−H bond activation by the Ir and Rh clusters, we conducted analyses of natural …

This research focuses on optimizing transition metal nanocatalyst immobilization and activity to enhance ethane dehydrogenation. Ethane dehydrogenation, catalyzed by thermally stable Irn (n = 8, 12, 18) atomic clusters that exhibit a cuboid structure, was studied using the B3LYP method with triple-ζ basis sets. Relativistic effects and dispersion corrections were included in the calculations. In the dehydrogenation reaction Irn + C2H6 → H−Irn−C2H5 → (H)2−Irn−C2H4, the first H-elimination is the rate-limiting step, primarily because the reaction releases sufficient heat to facilitate …


Industrial Policy And Renewable Energy: Trade Conflicts, Robert J. Carbaugh, Max St. Brown Jun 2012

Industrial Policy And Renewable Energy: Trade Conflicts, Robert J. Carbaugh, Max St. Brown

All Faculty Scholarship for the College of Business

Governments use industrial policy to promote the development of new industries and the creation and adoption of new technologies. Such policy involves subsidies granted to producers and consumers, usually for the purpose of correcting a market failure. Concerning renewable energies such as wind energy and solar energy, China, the United States, and the European Union provide extensive support to producers and consumers. This support has resulted in trade frictions among these nations. This paper discusses the relationship between industrial policy and trade disputes in renewable energy.
