Tuning Hydrophilicity and Active Sites of Fe-ZIF-8 to Enhance Methane-to-Formic Acid Conversion under Mild Conditions.
Direct selective oxidation of methane to formic acid (HCOOH) under mild conditions remains a major challenge. Here, we reported a surfactant-assisted in situ modification strategy that tuned the surface hydrophilicity and Fe active sites of Fe-ZIF-8. Among the three surfactants investigated, C16-modified FZ@C16 exhibit...
