Abstract：

Carbon　adsorbents　have　been　widely　used　to　remove　indoor　volatile　organic　compounds　(VOCs),　however,　the　proliferation　of　bacteria　on　the　carbon　adsorbents　may　deteriorate　the　indoor　air　quality　and　thus　pose　a　serious　threat　to　human　health.　Herein,　we　report　the　synthesis　of　antibacterial　porous　carbon　spheres　(carbonized　aminophenol-formaldehyde　resin,　CAF)　with　well-dispersed　Cu　species　via　an　in　situ　incorporation　of　Cu2+　during　the　polymerization　of　3-aminophenol-formaldehyde　resin　followed　by　a　thermal　carbonization　and　reduction　process.　Compared　with　CAF,　the　Cu/CAF-x　nanocomposites　with　Cu　loading　show　a　much　higher　specific　surface　area　(＞700　m2　g−1　vs.　569　m2　g−1　for　CAF).　In　addition,　the　pore　size　of　Cu/CAF-x　is　ranging　from　0.7　to　1.68　nm,　which　is　exactly　conducive　to　adsorb　the　toluene　molecules.　As　a　result,　the　toluene　adsorption　capacity　is　improved　from　123.50　mg　g−1　for　CAF　to　＞170　mg　g−1　for　Cu/CAF-x.　More　importantly,　such　adsorbents　possess　excellent　antibacterial　performance,　the　Cu/CAF-10　(10　wt%　of　Cu　loading)　with　a　concentration　of　50　μg　mL−1　can　completely　kill　the　E.　coli　within　30　min.　Our　work　paves　the　way　to　the　development　of　bifunctional　adsorbents　with　both　efficient　VOCs　adsorption　and　excellent　antibacterial　performance.　©　2023
