Mechanochemical Grafting Enables Fluorescein-Sensitized Cobalt-Based MOF for Visible-Light-Driven Hydrogen Evolution

Abstract

A rapid mechanochemical approach was developed to covalently graft an isothiocyanate dye onto an amino-functionalized metal-organic framework (MOF), enabling visible-light-driven hydrogen production via dye sensitization. This method offers a greener and more efficient alternative to conventional solution-based dye-labeling techniques, that typically requires excessive solvents and elevated temperature.
