Abstract The effective use of metal‐organic framework (MOF)‐based materials in the electrocatalytic hydrogen evolution reaction (HER) relies on understanding their structural and electronic properties. While structure morphology MOF‐derived catalysts significantly impact HER activity, tuning d‐band through modulation has emerged as a key factor optimizing catalytic performance. Techniques such composition tuning, heteroatom doping, surface modification, interface engineering were found to be methods for manipulating configuration and, turn, modulating d‐band. This review systematically explores design strategies by focusing modulation. It provides detailed discussion various – used modulate structure. Furthermore, establishes relationship between Gibbs free energy, modulation, supported both spectroscopic theoretical evidences.
