The　eradication　of　bacteria　and　the　degradation　of　organic　pollutants　in　contaminated　water　hold　paramount　importance　for　both　ecological　systems　and　human　health.　Herein,　we　report　the　development　of　a　bifunctional　material,　constructed　from　metal−organic　frameworks　(MOFs)　and　their　derived　metal/carbon　composites,　which　demonstrates　remarkable　efficacy　in　disinfecting　and　degrading　dyes　and　antibiotics.　Notably,　the　synthesized　Co-MOFs　and　their　derived　Co@C　composites　exhibit　a　progressive　enhancement　in　antibacterial　activity:　(i)　In　comparison　to　3D　Co-MOF　polyhedra,　2D　Co-MOF　nanosheets　demonstrate　superior　efficacy　in　killing　both　E.　coli　and　S.　aureus.　This　enhanced　antibacterial　performance　is　attributed　to　the　generation　of　a　higher　quantity　of　reactive　oxygen　species　and　the　unique　nanosheet　structure.　(ii)　Following　heat　treatment　of　the　2D　Co-MOFs,　carbon-encapsulated　cobalt　nanoparticles　(Co@C)　are　obtained.　These　nanoparticles　further　reduce　the　minimum　inhibitory　concentration　(MIC)　and　minimum　bactericidal　concentration　(MBC)　values　compared　to　the　pristine　2D　Co-MOFs.　(iii)　Additionally,　the　carbon　layers　impart　exceptional　photothermal　properties　to　the　materials,　leading　to　a　further　enhancement　in　antibacterial　efficacy.　With　irradiation　with　NIR　for　just　10　min,　the　bactericidal　rates　against　E.　coli　and　S.　aureus　can　be　as　high　as　97　%　and　100　%,　respectively.　Furthermore,　the　cobalt　nanoparticles　within　the　carbon　layers　serve　as　catalysts　for　Fenton-like　catalytic　degradation　of　organic　pollutants　in　the　presence　of　peroxymonosulfate.　Nearly　100　%　of　cationic　Methylene　Blue　and　anionic　Congo　Red,　as　well　as　77　%　of　Enrofloxacin,　can　be　degraded　within　60　seconds.　©　2025　Elsevier　B.V.
