Interfacial Electron-Proton Dual Modulation of Fe Single-Atom Catalyst by α-MoC for O2 Activation and Lignin Depolymerization.
Efficient O2 activation under mild conditions is central to oxidative biomass valorization, yet single-atom catalysts often suffer from sluggish proton-coupled oxygen intermediate conversion, particularly because of overly strong *OH adsorption. Inspired by the cooperative electron and proton management in cytochrome c...
