Abstract Adsorption and photocatalysis are promising strategies to remove pollutants of dyes and antibiotics from wastewater. In this study, we demonstrate a rapid microwave-assisted hydrothermal route for the assembly of 2D copper-porphyrin Metal-Organic Frameworks (Cu-TCPP MOFs) within 1 h. The resulting 2D Cu-TCPP nanosheets with excellent crystallinity and a large surface area (342.72 m2/g) exhibited outstanding adsorption performance for typical dyes with adsorption capacities of about 185 mg/g for rhodamine B, 625 mg/g for methylene blue, and 290 mg/g for Congo red, respectively, as well as for representative antibiotics with adsorption capacities of about 130 mg/g for oxytocin, 150 mg/g for tetracycline, and 50 mg/g for norfloxacin, respectively. Meanwhile, the as-prepared 2D Cu-TCPP showed good photocatalytic degradation activity of pollutants after adsorption under irradiation by visible light, reaching removal efficiencies of 81.2 and 86.3% toward rhodamine B and norfloxacin, respectively. These results demonstrate the promising potential of 2D Cu-TCPP for use in the removal of contaminants from wastewater. Keywords Two-dimensional MOFs . Microwave synthesis . Antibiotics .

Introduction Water contamination from dyes and antibiotics has become an increasingly critical problem over the past few decades due to the rapid development of industrial printing and aquaculture (Evans et al. 2019; Gao et al. 2019; Sun et al. 2018). In particular, antibiotics can seriously impact the environment and
may even cause cancer, deformations, and mutations to humans (Dai et al. 2019; Gao et al. 2019). Conventional methods of treating wastewater contaminated by organics usually include wet air oxidation, electrocatalytic oxidation, ultrasonic oxidation, and biochemical oxidation (Wang and Mi 2017; Yang et al. 2017b). However, each of these methods has operational disadvantages: wet air oxidation methods
