MOF-based and MOF-derived electrocatalysts for anodic reactions coupled with hydrogen evolution

Abstract

Energy-efficient and sustainable hydrogen production is essential for mitigating environmental pollution and enabling the energy transition, yet practical water electrolysis is hindered by the sluggish, energy-intensive oxygen evolution reaction (OER). Replacing the OER with thermodynamically and kinetically favorable value-added anodic reactions can lower the required voltage while co-producing useful chemicals and, in some cases, enabling wastewater remediation. Metal–organic frameworks (MOFs) provide a distinctive catalyst platform for such hybrid electrolysis: their modular architectures enable tunable compositions, deliberately engineered active sites and microenvironments, and adjustab..
