However, its sluggish multi\u2010electron kinetics and poor mass transport properties at high current densities have hindered its large\u2010scale implementation. In this work, we have developed a high\u2010entropy monolithic aerogel (HE\u2010AG) electrode that ingeniously integrates the electronic environmental diversity inherent to high\u2010entropy systems with the characteristic porous architecture of aerogels. This HE\u2010AG electrode demonstrates exceptional OER catalytic performance, achieving a current density of 500\u00a0mA cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    at an overpotential of merely 208\u00a0mV. Combined structural characterization and theoretical calculations reveal that the unique electronic environment of the HE\u2010AG is the key to independently modulating the multiple elementary electron\u2010transfer steps involved in the OER. Specifically, the precise tuning of the\n                    <jats:italic>p<\/jats:italic>\n                    \u2010band center of the lattice oxygen effectively balances the binding strength between reaction intermediates and active sites. In situ Raman spectroscopy further elucidates the roles played by Cr and V within the high\u2010entropy system, demonstrating that their partial leaching during the OER significantly promotes the electrochemical reconstruction of the HE\u2010AG into the active metal oxyhydroxide phase. This synergistic strategy can be extended to serve as a general design rule for heterogeneous catalytic applications.\n
