Ligand‐Intercalated MOFs Enable Reaction‐Pathway Engineering in Biomass Electrooxidation via Steric and π‐Electronic Microenvironment Control

open access: yesAngewandte Chemie, EarlyView.
Through ligand length and π‐electron density modulation, metal–organic frameworks (MOFs) improve mass transport and hydrogen atom transfer (HAT), thus improving biomass electrooxidation. ABSTRACT Controlling reaction pathways in electrocatalytic biomass upgrading remains challenging because mass transport, substrate adsorption, and elementary kinetics ...
