摘 要：The development of a room temperature (<50 C) fuel cell that would use a generally available fuel such as JP8 would be most valuable. However there are no known catalysts that can selectively activate the CC bonds of such fuels at such temperature. The goal of this project was to investigate whether it is plausible to develop such catalysts. To do this we used validated first-principles (quantum mechanics) based simulations to investigate the barriers for alkyl carbon-carbon cleavage for two prototypical systems: A metal alloy catalyst and an organometallic cluster catalyst. That might serve as an anode for electrochemical power generation. For the metal alloy catalyst we used a top-down approach where we determined the bond energies to the alloy catalyst to various fuel fragments necessary to achieve room temperature decomposition of butane and oxidation to CO2. For organometallic cluster catalyst we used a bottom-up strategy, determining specific metals, ligand compositions, solvents and operating conditions to evaluate which conditions could lead to reasonable rates at room temperature.
