Bayesian Exploration of Metal‐Organic Framework‐Derived Nanocomposites for High‐Performance Supercapacitors

David Gryc, Pritam Banerjee, Felipe Jacques Lima Duarte, Joerg Ralf Jinschek et autres

Metal‐organic framework (MOF)‐derived materials are promising candidates for energy storage applications, particularly as supercapacitors, owing to their high porosity, tunable compositions, and pseudocapacitive behavior. However, performance optimization traditionally relies on resource‐intensive trial‐and‐error methods with limited insight into complex structural transitions. To address …
