Multicomponent Interface and Electronic Structure Engineering in Ir-Doped CoMO₄–Co(OH)₂ (M = W and Mo) Enable Promoted Oxygen Evolution Reaction

Inorganic Chemistry, Journal Year: 2024, Volume and Issue: 63(34), P. 16037 - 16046

Published: Aug. 9, 2024

The core principles of multicomponent interface and electronic structure engineering are essential in designing high-performance catalysts for the oxygen evolution reaction (OER). However, combining these aspects within a catalyst is significant challenge. In this investigation, novel approach involving development hybrid Ir-doped CoMO4–Co(OH)2 (M = W Mo) hollow nanoboxes was introduced, enabling remarkably efficient water oxidation electrocatalysis. Constructed from ultrathin nanosheet-assembled nanoboxes, structures boast wealth active centers intermediate species, which turn enhance both charge transfer mass transport capabilities. Moreover, compelling synergistic effects arising interaction between CoMO4 Co(OH)2 significantly bolster OER electrocatalysis by facilitating electron transfer. introduction Ir atoms serves to strategically adjust structure, fine-tune its state, operate as electrocatalysis, thus diminishing overpotential. This configuration results Ir-CoWO4–Co(OH)2 Ir-CoMoO4–Co(OH)2 exhibiting impressively low overpotentials 252 261 mV, respectively, 10 mA cm–2. Utilized conjunction with Pt/C two-electrode system overall splitting, mere 1.53 V cell potential needed achieve desired cm–2 current density.
