Enhancing　the　generation　of　active　groups　is　of　great　significance　for　alleviating　the　catalyst　deactivation　of　formaldehyde　(HCHO)　by　accelerating　the　decomposition　of　intermediate　products.　Herein,　an　electric-field-enhanced　catalytic　effect　was　proposed　for　the　efficient　capture　and　degradation　of　HCHO　base　on　carbon　cloth　loaded　manganese　oxide　catalyst　(MnOx-CC).　Under　the　action　of　electric　field,　MnOx　can　generate　more　hydroxyl　radicals　(•OH)　and　superoxide　radicals　(•O2-),　thus　accelerating　the　degradation　of　HCHO　and　intermediates　at　room　temperature.　After　the　introduction　electric　field　(∼1　×104　V/m),　•O2-　and　•OH　radical　on　the　surface　of　MnOx-CC　catalyst　can　be　increased　by　8　times　and　23　times,　respectively.　At　weight　hourly　space　velocity　of　300,000　mL/(gcat　h)　for　∼15　ppm　HCHO,　MnOx-CC-Electric　Field　catalyst　reached　the　removal　efficiency　of　99.4%,　and　the　CO2　conversion　efficiency　of　81.2%,　without　decrease　significantly　within　80　h.　Theoretical　calculation　shows　that　the　electric　field　can　increase　the　electron　state　density　of　Mn　atom　at　the　Fermi　level　and　reduce　the　adsorption　energy　of　HCHO,　O2　and　H2O,　thus　promoting　the　generation　of　active　groups　and　degradation　of　intermediate　products.　The　electric-field-enhancement　catalytic　effect　provides　a　new　approach　for　the　degradation　of　Volatile　Organic　Compounds.　©　2023　Elsevier　B.V.
