A 3D copper−organic framework of HKUST-1 (MOF-199) was synthesized via solvothermal reaction of Cu(NO3)2∙3H2O and 1,3,5-Benzenetricarboxylic acid (BTC) according to literature methods. HKUST-1 was further sensitized by adsorbing trichromatic dyes photosensitizers of BY24 (C. I. Basic Yellow 24), BR14 (C. I. Basic Red 14) or MB (Methylene Blue) molecules from their aqueous solutions to assemble three novel composites of BY24@HKUST-1, BR14@HKUST-1 and MB @HKUST-1 for the first time. Compared with as-synthesized HKUST-1, dyes photosensitizers sensitized HKUST-1 demonstrate enhanced and tunable photodegradation performances towards large sized RB13 (C. I. Reactive Blue 13) under visible-light irradiation. The interesting findings may open up more applications of dyes sensitized composites and such sensitization strategy could be widely adopted to design and create versatile materials towards disposing some intractable organic contaminants.
