WebMar 4, 2024 · Abstract. A combination of periodic density functional theory (DFT, PW91-GGA) calculations, reaction kinetics experiments, and mean-field microkinetic modeling is used to derive insights on the reaction mechanism and determine the nature of the active site under reaction conditions for the vapor-phase decomposition of formic acid (FA, … Following the order in the above experimental section, we begin by discussing the as-prepared MFe phases (M:Fe = 3:1, α-MFe LDHs). DFT calculations indicate that α-MFe LDHs adopt the structure of hydrotalcite (Mg6Al2CO3(OH)16·4H2O), which is the archetypical LDH material with its characteristic three layer … See more We studied the redox chemistry of NiFe LDH and CoFe LDH (M:Fe = ~3:1) using cyclic and linear sweep voltammetry (CV and LSV) and … See more To follow the phase transition of the catalysts from their as-synthesized precursor state into the catalytically active states, synchrotron … See more Beginning with the elucidated bulk structures described above, we evaluated the steady state of the (01–10) surface of γ-NiOOH, γ-NiFe … See more
