| Abstract: | 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. [Display omitted] • Bifunctional Co-MOFs and their derived Co@C with antibacterial and catalytic properties. • Superior antibacterial activity of 2D Co-MOF nanosheets over 3D Co-MOF polyhedra. • Co-MOF-derived Co@C composites further reduce MIC and MBC values. • Photothermal effect of Co@C enables rapid bacterial eradication. • Fenton-like catalytic degradation of dyes and antibiotics by Co@C.
