Abstract Electro‐Fenton process stands out as a highly promising approach for generating reactive oxygen‐containing radicals to address the escalating issue of environmental pollution. However, long‐term goal application necessitates ongoing pursuit high‐quality catalysts with both sufficient activity and stability. Herein, general route is reported large‐scale synthesis amorphizing porous bimetallic metal‐organic framework (MOF) spheres Zn─O─Fe structure coordination deficiency through facile low‐cost ligand competition. Assisted by modulator, deprotonation terephthalic acid accelerated rapid amorphous MOF successfully achieved at room temperature. As inactive metal Zn introduced into clusters MOFs, cycling efficiency Fe 3+ /Fe 2+ improved secondary building unit constructed, greatly accelerating electron conduction rate. Compared crystalline spindle cMIL‐88B(Fe 2 Zn) traditional solvothermal route, aMIL‐88B(Fe has unique spherical larger surface area, higher conductivity, more exposed active sites. Endowed textural chemistry, exhibits superior catalytic in degradation refractory organic pollutants. The progress offers feasible way rational design iron‐based hybrid materials tunable structures enhance properties various applications.
