Abstract: Taking a Stab at Alchemy: Nanostructured Early Transition Metal Carbides and Nitrides
The insertion of carbon and nitrogen into the interstitial sites in Mo and V can transform these metals into materials with properties that are similar to those of noble metals like Pt and Au. For example, Michel Boudart, a former member of the Stanford faculty, was among the first to report similarities between the catalytic properties of tungsten carbides and Pt, one of the most important catalytic materials known. Since these early discoveries, interstitial metal carbides and nitrides have been investigated for a variety of catalytic and energy storage applications. This talk will describe our work to understand the interactions of hydrogen and metals with these materials. Hydrogen is a reactant or product in a number of important catalytic and electrocatalytic reactions including those required for biomass conversion. Interestingly we found evidence that subsurface hydrogen influences surface catalytic reactions for some metal nitrides. Because carbides and nitrides can be produced with high surface areas, there is also interest in using them as support materials. A better understanding of the relevant interactions would enable the rational design of carbide and nitride supported metal catalysts.
