Session: Solid-State Inorganic Chemistry:

The poster reports the preliminary results from the project “Exploring Base Metal Intermetallic Compounds to Substitute Platinum Catalysts in Heterogeneous Hydrogenation of Unsaturated Hydrocarbons” funded by ACS Petroleum Research Fund. Base metal binary intermetallic compounds, such as Ni₃Mo and Co₃W, were prepared using arc-melting and high temperature annealing. The loading compositions and annealing temperatures were tuned to improve the purity and crystallinity of the samples and the crystal structures were studied with X-ray diffraction. The electronic structures of these compounds were also calculated with first-principle quantum mechanics calculations and compared with Pt. According to the “like electronic structure, like properties” rationale, these binary intermetallic compounds are potential substitutes for Pt in catalyzing hydrogenation reactions of unsaturated hydrocarbons.
