The key to lowering the energy barrier of the oxygen evolution reaction (OER) is to build the interface properly and increase oxygen vacancies. In this work, a nickel phosphide on nickel foam-derived catalyst with rich O_v and a multi-interfacial nanosheet intercalated structure, labeled as (Fe,La)Ni₂P-r, was created on nickel foam by using a straightforward two-step technique, namely hydrothermal and electrochemical oxidation. The addition of Fe–La creates a heterogeneous interface on the catalyst surface, causes electron transfer and redistribution, and lowers the binding energy of intermediates. At the same time, connected with DFT, it was discovered that the addition of Fe–O_v–La significantly lowered the Gibbs free energy of the reaction process, enhanced the intermediate species adsorption, and hastened the oxygen release.

While <em>ab initio</em> molecular dynamics is often required to sample correctly the various states described by the system, the level of theory also has a crucial impact. In the present work, we report the determination of accurate barriers for a type B isomerization of a monobranched C7 alkene (4-methyl-hex-1-ene) into a dibranched tertiary cation inside a protonated chabazite zeolite. This is done by using the Machine Learning Thermodynamic Perturbation Theory (MLPT) at the Random Phase Approximation (RPA) level, on the basis of blue-moon sampling dynamic data obtained at the Generalized Gradient Approximation (GGA) level (PBE+D2). The comparison of PBE+D2 and RPA profiles shows that the former overstabilizes cationic intermediates with respect to neutral ones. The transition state of the isomerization is a non-classical edge protonated cyclopropane, the stabilization of which is lower than that of the π-complex when PBE+D2 is replaced by RPA, but higher than that of the classical tertiary carbenium. Consequently, the backward isomerization barrier is decreased. Applying the MLPT approach to recompute the free energy barriers with various dispersion correction schemes to the PBE energies shows that none of the schemes is sufficient to improve both the forward and backward barriers with respect to the RPA reference. These data complement previously determined alkene cracking barriers [Rey <em>et al.</em>, <em>Angew. Chem., Int. Ed.</em>, 2024, <strong>63</strong>, e202312392], thanks to which it is possible to compare the presently determined barriers with reference experimental data [Schweitzer <em>et al.</em>, <em>ACS Catal.</em>, 2022, <strong>12</strong>, 1068–1081]. The agreement with experiments is significantly improved at the RPA with respect to GGA.
