Understanding the mechanisms of action for base metal catalysis of transformations typically associated with precious metals is essential for the design of technologies for a sustainable energy economy. Isolated transition-metal and post-transition-metal catalysts on oxides such as silica are generally proposed to effect hydrogenation and dehydrogenation by a mechanism featuring either sigma-bond metathesis or heterolytic bond cleavage as the key bond activation step. In this work, an organovanadium(III) co...
Mechanochemical and volume combustion synthesis of ZrB2
Akgun, Baris; ÇAMURLU, HASAN ERDEM; Topkaya, Yavuz Ali; SEVİNÇ, NACİ (Elsevier BV, 2011-09-01)
Formation of ZrB2 by volume combustion synthesis (VCS) and mechanochemical process (MCP) from ZrO2-Mg-B2O3 was studied. Production of ZrB2 by VCS in air occurred with the formation of side products, Zr2ON2 and Mg3B2O6 in addition to MgO and ZrB2. Zr2ON2 formation was prevented by conducting VCS experiments under argon. Wet ball milling was applied to the VCS products before leaching for easier removal of Mg3B2O6 phase. MgO and Mg3B2O6 were removed from wet ball-milled products by leaching in 5 M HCI for 2.5...

Mechanochemical and combustion synthesis of CeB6
Akgun, Baris; SEVİNÇ, NACİ; ÇAMURLU, HASAN ERDEM; Topkaya, Yavuz Ali (Carl Hanser Verlag, 2013-04-01)
CeB6 powder was prepared via combustion synthesis (CS) and mechanochemical processing (MCP) methods starting from CeO2, B2O3 and Mg powder mixtures. In CS, reactant mixtures were ignited in a preheated pot furnace under argon atmosphere. Products contained CeB6, MgO and Mg3B2O6, as revealed by X-ray diffraction analysis. After leaching in 1 M HCl for 15 h, MgO was removed but Mg3B2O6 could not be removed from the products. Ball milling of products in ethanol prior to leaching made the removal of Mg3B2O6 pos...
