Magnesium ferrite/sulfur‐doped graphitic nitride (MFO/SCNNS) heterostructure has been developed via sonication‐assisted deposition of zero‐dimensional MFO over the surface of two‐dimensional SCN nanosheets. Additionally, the prepared nanocomposite material has been characterized by several analytical characterization techniques including XRD, Fourier transform infrared (FT‐IR), high‐resolution transmission electron microscopy (HR‐TEM), selected‐area electron diffraction (SAED), energy‐dispersive spectrometry (EDS), Brunauer–Emmett–Teller (BET), vibrating sample magnetometer (VSM), UV–Vis. spectroscopy, electron spin resonance(ESR), and X‐ray photoelectron spectroscopy (XPS) which indicated the existence of strong interfacial interactions via heterojunction formation between MFO and SCNNS. The as prepared nanocomposite, especially MFO:SCNNS (1:1) (having 1:1 mass ratio of MFO to SCNNS), offered impressive photo‐response for the complete degradation of Erythrosine B and Indigo Carmine within 30 min under direct solar light irradiation. The enhanced photoactivity of the MFO:SCNNS (1:1) was also confirmed by the photoluminescence, photocurrent and electrochemical impedance spectroscopy. The Mott–Schottky analysis also depicts the formation of p‐n heterojunction at the interface of MFO and SCNNS, responsible for the enhanced photoactivity. Additionally, the degradation process has also been studied using mass spectrometry, UV–Vis, and ESR spectral analysis. The trapping experiments were also conducted to confirm the formation of active radical species during the photodegradation reaction. Furthermore, the nanocomposite photocatalytic material offered excellent stability and reusability and thus can serve as an effective candidate for environmental remediation application such as real waste water treatment.

Today's world is on the verge of antibiotic pollution by humans, veterinary therapeutics polluting our water body, and on account of the scarcity in advanced water treatment techniques in the wastewater treatment plants (WWTPs). It is of enormous importance to have an insight into various kinds of antibiotics and their attributes. The primary aspects of antimicrobial resistance caused by antibiotic pollution in the environment have been briefly enlightened. Here the nature and occurrence of antibiotics accumulation in the environment and a world pollution scenario have been illustrated. Adsorption and photocatalysis are the most standard techniques used for remediation. The well‐known nano photocatalyst heterostructure materials Titanium dioxide (TiO2), bismuth (Bi) materials are also utilized as the main frame materials for the composites and heterostructures. Alternatively, the porous carbon‐based materials and metal‐organic framework (MOF) materialsare entitled to their excellent adsorption capability. This review portrays comprehensive insight into the advances and breakthroughs made so far by different heterostructures and nanocomposite materials for antibiotics removal and provides a road map to future researchers towards a more efficient water treatment system.

“…The other sources of antibiotic pollution are hospitals, households, and animal husbandry (Cao et al 2017 ). It is now well known that synthetic pharmaceutical compounds (SPC) have severe phyto-toxicological and genotoxicity, endocrine disruption, and aquatic toxicity in the environment (Zhao et al 2019 ). Nalidixic acid (NAL) is a well-known SPC.…”

The menace posed by antibiotic contamination to humanity has increased due to the absence of efficient antibiotic removal processes in the conventional waste water treatment methods from the hospitals, households, animal husbandry, and pharma industry. Importantly, only a few commercially available adsorbents are magnetic, porous, and have the ability to selectively bind and separate various classes of antibiotics from the slurries. Herein, we report the synthesis of a coral-like Co@Co 3 O 4 /C nanohybrid for the remediation of three different classes of antibiotics — quinolone, tetracycline, and sulphonamide. The coral like Co@Co 3 O 4 /C materials are synthesized via a facile room temperature wet chemical method followed by annealing in a controlled atmosphere. The materials demonstrate an attractive porous structure with an excellent surface-to-mass ratio of 554.8 m 2 g −1 alongside superior magnetic responses. A time-varying adsorption study of aqueous nalidixic acid solution on Co@Co 3 O 4 /C nanohybrids indicates that these coral-like Co@Co 3 O 4 /C nanohybrids could achieve a high removal efficiency of 99.98% at pH 6 in 120 min. The adsorption kinetics data of Co@Co 3 O 4 /C nanohybrids follow a pseudo-second-order reaction kinetics suggesting a chemisorption effect. The adsorbent has also shown its merit in reusability for four adsorption-desorption cycles without showing significant change in the removal efficiency. More in-depth studies validate that the excellent adsorption capability of Co@Co 3 O 4 /C adsorbent attributing to the electrostatic and π–π interaction between adsorbent and various antibiotics. Concisely, the adsorbent manifests the potential for the removal of a wide range of antibiotics from the water alongside showing their utility in the hassle-free magnetic separation.
