Theory Study of AlCl Disproportionation Reaction Mechanism on Al (110) Surface

Abstract: The surface disproportionation reaction mechanism of aluminum subchloride on aluminum (110) surfaces has been investigated using the plane-wave density functional theory (DFT). Three possible reaction mechanisms of AlCl disproportionation reaction on aluminum (110) surfaces have been taken into account; the reactants and products structures have been optimized, transition states have been confirmed, and activation energy has been calculated. The adsorption energy of reactants and the desorption energy of produ… Show more

“…A smearing width is 0.005 Ha. The transition states of C 2 H 2 selective hydrogenation were obtained by the complete linear synchronous transit/quadratic synchronous transit (LST/QST) technique. , TS confirmation and frequency analysis were further carried out to verify the accuracy of the transition state.…”

“…Density functional theory (DFT) calculations were applied to elucidate the reaction mechanism between gases and solid surfaces at atomic scale. 26,27 Pentlandite being the primary source for nickel extraction, some computational studies have attempted to elucidate the electronic structure of pentlandite. Mkhonto et al modeled the interaction of O 2 with the (110) surface of pentlandite (Fe 5 Ni 4 S 8 ).…”

“…The following methods are used to extract aluminum from coarse Al-Si alloys. The first involves disproportionation reactions of aluminum in the coarse Al-Si alloy or Al-Si-Fe alloy by reaction with AlCl 3 or AlF 3 to form AlCl or AlF gas at high temperature, which is separated from Si and Fe and reverted to aluminum, AlCl 3 or AlF 3 at low temperature [16,17]. The second method involves the separation of aluminum by molten salt electrolysis.…”
