Photodegradation of amoxicillin and ciprofloxacin using green‐synthesized copper oxide nanoparticles
Transition metal oxide nanoparticles (M x O y NPs) present unique physicochemical properties and high surface reactivity, making them useful in environmental processes. In metal nanoparticle classification, cupric oxide nanoparticles (CuONPs) are considered some of the most attractive oxide materials; they are naturally abundant, non‐toxic, and inexpensive. In this research work, CuONPs were synthesized via a biological method, using an aqueous extract of Hibiscus rosa‐sinensis flowers ( H. rosa‐sinensis , ExHrsF), which acts as both a reducing and stabilizing agent (CuONPs/ExHrsF). The characterization of CuONPs/ExHrsF was performed using various analytical techniques, including Fourier transform infrared spectroscopy (FTIR), scanning transmission electron microscopy (STEM) coupled with X‐ray energy‐dispersive spectroscopy (EDS), X‐ray diffraction (XRD), dynamic light scattering (DLS), and Zeta potential ( ζ ). The synthesized CuONPs/ExHrsF was utilized as photocatalysts in the degradation of amoxicillin (AMX) and ciprofloxacin (CIP) in water, achieving efficiencies approaching 100% within a 3‐h timeframe.

Membranas poliméricas dopadas con nanopartículas de cobre sintetizadas por química verde empleando un extracto de azafrán
Recientemente, el interés por las nanopartículas metálicas (MNPs) se ha incrementado significativamente, debido a las propiedades especiales y aplicaciones potenciales que presentan en áreas diversas. Las nanopartículas de cobre (CuNPs) en particular, han atraído considerablemente la atención debido a sus propiedades conductoras, catalíticas, ópticas, eléctricas y antibacterianas. En la presente investigación se desarrolló una metodología para soportar, por métodos in situ y ex situ, las CuNPs, sintetizadas por química verde empleando el extracto acuoso de azafrán (ExCs), en membranas poliméricas de ultrafiltración. Los nanocompositos de CuNPs/ExCs se caracterizaron por ATR-FTIR, microscopia electrónica de barrido de emisión de campo (FESEM-EDS), XRD, análisis termogravimétrico (TGA) y análisis de permeabilidad y grado de ensuciamiento. Los resultados de permeabilidad obtenidos muestran que el método empleado para soportar las CuNPs en la membrana polimérica, afecta la permeabilidad y la velocidad de ensuciamiento de las mismas. Los compositos obtenidos empleando el método in situ (utilizando borohidruro de sodio o ácido ascórbico como agente reductor) presentaron los mejores resultados de permeabilidad (1.14x10-8 m/Pa.s y 1.94x10-9 m/Pa.s, respectivamente) y un grado ensuciamiento superficial de la membrana del 28.2 y 2.89% respectivamente. Lo anterior demuestra que las CuNPs, repelen el material orgánico que provoca el ensuciamiento de las membranas poliméricas.
