Cu²⁺ coordination-induced in situ photo-to-heat on catalytic sites to hydrolyze β-lactam antibiotics pollutants in waters.

ABSTRACT: For degradation of β-lactam antibiotics pollution in waters, the strained β-lactam ring is the most toxic and resistant moiety to biodegrade and redox-chemically treat among their functional groups. Hydrolytically opening β-lactam ring with Lewis acid catalysts has long been recognized as a shortcut, but at room temperature, such hydrolysis is too slow to be deployed. Here, we found when Cu²⁺ was immobilized on imine-linked COF (covalent organic framework) (Cu²⁺/Py-Bpy-COF, Cu²⁺ load is 1.43 wt%), as-prepared composite can utilize the light irradiation (wavelength range simulated sunlight) to in situ heat anchored Cu²⁺ Lewis acid sites through an excellent photothermal conversion to open the β-lactam ring followed by a desired full-decarboxylatio
