“…Results obtained from the current study were compared with previously reported photocatalysts for the degradation of CIP and AMP, as shown in Table 1 . The degradation efficiency exhibited by NdFe 2 O 4 @g-C 3 N 4 for the degradation of CIP is higher than values recently reported for BiVO 4 , 61 Cu 2 O/MoS 2 /rGO, 62 TiO 2 /SnO 2 composite 63 and CeO 2 /g-C 3 N 4 . 64 The regeneration capacity expressed by NdFe 2 O 4 @g-C 3 N 4 also compares favourably with other photocatalysts.…”

“…The synthesized materials were able to degrade the tetracycline by up to 96.7% within 2 h of light irradiation . Interestingly, complete degradation of tetracycline has been reported by Selvamani et al after 10 min of visible-light irradiation . The authors combined both visible light and ultrasonic irradiation to achieve these remarkable findings.…”

Visible-light-responsive photocatalytic materials have a multitude of important applications, ranging from energy conversion and storage to industrial waste treatment. Molybdenum disulfide (MoS 2 ) and its variants exhibit high photocatalytic activity under irradiation by visible light as well as good stability and recyclability, which are desirable for all photocatalytic applications. MoS 2 -based materials have been widely applied in various fields such as wastewater treatment, environmental remediation, and organic transformation reactions because of their excellent physicochemical properties. The present review focuses on the fundamental properties of MoS 2 , recent developments and remaining challenges, and key strategies for tackling issues related to the utilization of MoS 2 in photocatalysis. The application of MoS 2 -based materials in visible-light-induced catalytic reactions for the treatment of diverse kinds of pollutants including industrial, environmental, pharmaceutical, and agricultural waste are also critically discussed. The review concludes by highlighting the prospects of MoS 2 for use in various established and emerging areas of photocatalysis.

“…The photocatalytic degradation test of the synthesized g-C 3 N 4 /CuO composites were designed for the degradation of antibiotic drugs including TC and CIP in the glass reactor equipped with UV lter (EasyMax 102 Advanced Thermostat system model: A9616-07) under 200 W Hg-Xe lamp. In a distinctive procedure as mentioned in the previous work [30], prior to exposure of light, the reaction suspension (25 mg of catalyst + 15 mg/L of antibiotic solution in 100 mL) was stirred under magnetic stirrer in the dark for 1 hour to reach the adsorption-desorption equilibrium. After that, the reaction suspension was exposed to light as initiating the photocatalytic degradation reactions, the equal portions (1 mL) of the reaction suspension was taken at different time intervals to analyze the concentration of reaction solution.…”

Nowadays, the removal of pollutants and sensing of trivial quantity of heavy metal ions for the prevention of environmental pollution by graphene based materials is attractive research in the eld of nanotechnology. Herein, we have designed for the fabrication of a series of g-C 3 N 4 /CuO composite by using one-step microwave-assisted synthesis convoyed by the calcinations for the degradation of antibiotic drugs and detection of nano-molar range of toxic heavy metal ions for the development of heterostructured composites. The synthesized g-C 3 N 4 /CuO composites were analyzed and characterized by TEM images, powder XRD, FTIR, N2 adsorption-desorption isotherms, UV-vis DRS, and photoluminescence techniques to know the structure, phase, surface area, absorption region, bandgap, and size of the composites. From the observation of TEM and XRD measurements, g-C 3 N 4 /CuO composites have hexagonal shape with average diameter of the particles is 25 ± 5 nm. The observed band gap values from UV-vis DRS for g-C 3 N 4 nanosheets and CuO NPs are 2.64eV and 1.72 eV. The N 2 adsorption-desorption isotherm of the synthesized g-C 3 N 4 /CuO composite has prodigious speci c surface area (32.47 m 2 /g), which is the evident for superior heterogeneous catalytic applications.Therefore, the synthesized g-C 3 N 4 /CuO composites were tested for the heterogeneous photocatalytic degradation of antibiotics such as tetracycline (TC) and cipro oxacin (CIP) under UV light illumination, it shows as almost complete degradation was observed within 1 hour due to the matching optical band gap and internal charge transfer of excitons with in the heterojunction surface among g-C 3 N 4 and CuO in the composite. Moreover, the enhanced catalytic performance of g-C 3 N 4 /CuO composite over the containing the individual components (g-C 3 N 4 and CuO) due to the high surface area and tiny particles of CuO were randomly deposited on the surface of g-C 3 N 4 nanosheets. The catalytic reduction reaction kinetics for the degradation of antibiotics trails as pseudo-rst order kinetic equation and reused the catalyst for 5 consecutive cycles without noteworthy loss of catalytic activity. Moreover, the synthesizedg-C 3 N 4 /CuO composites were used as a prominent uorescence sensing probe for the selective detection of toxic heavy metal ions in nano-molar range of concentration and selective sensing of Pb 2+ among various metal ions by the uorometric analysis was observed.
