Abstract：

Improving　the　adsorption　kinetics　of　metal-oxide　catalysts　is　critical　for　the　enhancement　of　catalytic　performance　in　heterogeneous　catalytic　oxidation　reactions.　Herein,　based　on　the　biopolymer　pomelo　peels　(PP)　and　metal-oxide　catalyst　manganese　oxide　(MnOx),　an　adsorption-enhanced　catalyst　(MnOx-PP)　was　constructed　for　catalytic　organic　dyes　oxidative-degradation.　MnOx-PP　shows　excellent　methylene　blue　(MB)　and　total　carbon　content　(TOC)　removal　efficiency　of　99.5　%　and　66.31　%　respectively,　and　keeps　the　long-lasting　stable　dynamic　degradation　efficiency　during　72　h　based　on　the　self-built　continuous　single-pass　MB　purification　device.　The　chemical　structure　similarity　and　negative-charge　polarity　sites　of　the　biopolymer　PP　improve　the　adsorption　kinetics　of　organic　macromolecule　MB,　and　construct　the　adsorption-enhanced　catalytic　oxidation　microenvironment.　Meanwhile,　the　adsorption-enhanced　catalyst　MnOx-PP　obtains　lower　ionization　potential　and　O2　adsorption　energy　to　promote　the　continuous　generation　of　active　substance　(O2*,　OH*)　for　the　further　catalytic　oxidation　of　adsorbed　MB　molecules.　This　work　explored　the　adsorption-enhanced　catalytic　oxidation　mechanism　for　the　degradation　of　organic　pollutants,　and　provided　a　feasible　technical　idea　for　designing　adsorption-enhanced　catalysts　for　the　long-lasting　efficient　removal　of　organic　dyes.　©　2023
