Ultralow iridium loading with three-layer core/shell structured IrFe@Fe3O4@NiFe LDH as efficient bifunctional electrocatalysts for overall water splitting

Recent Developments in Nickel-Based Layered Double Hydroxides for Photo(-/)electrocatalytic Water Oxidation

“…In addition to noble metals, researchers have also explored the utilization of other compound materials to construct LDH-based composite catalysts. − For instance, Yu et al successfully prepared a original layered FeNi-LDH/Ti 3 C 2 -Mxene nanocomposite through the in situ assembly of ultrathin FeNi-LDH on Ti 3 C 2 -Mxene under reflow conditions. This catalyst showed outstanding performance for the OER, i.e., a small overpotential of approximately 240 mV at 10 mA cm –2 and a low Tafel slope of 43 mV dec –1 .…”

Iridium Nanoparticles on SPIONs as a Catalyst for N‐Heteroarene and Styrene Hydrogenation Reactions and their DFT Studies

“…[64,65] This observation can be attributed to the fact that Fe 3 O 4 can more readily engage N-bearing heterocyclic compounds than other supports. In addition to the effective metal-support synergistic interaction of Ir and Fe 3 O 4 in the IrNPs@SPIONs catalyst, [66,67] the Lewis acidic nature of magnetite immensely contributes to bringing the N-bearing heterocyclic substrate closer to the catalytic metal center (Ir) and hence promoting their subsequent hydrogenation reaction. Also, Fe 3 O 4 support may promote Ir metal particle dispersion on its surface, resulting in more active catalyst sites in the metal center enhancing the prospect of hydrogenation activity.…”
