“…It is already established that the norfloxacin antibiotic is photocatalytically degraded by the oxidation process in an aqueous medium. − The free radicals and holes trapping tests provide more insight into the photocatalytic mechanism of norfloxacin degradation in aqueous solution using RGO–SnSe catalysts. The role of different oxidative species was studied by using 2-propanol (OH · scavenger), EDTA-Na 2 (h + , hole scavenger), and purging N 2 gas (O 2 –· scavenger). − The temporal photodegradation and degradation efficiency of RGO–SnSe composite for different scavengers are graphically represented in Figure S6A,B in SI, respectively.…”

A visible-light-responsive photocatalyst, comprising reduced graphene oxide (RGO) modified tin selenide (SnSe), was fabricated via a cost-effective, one-pot, easy-to-achieve, single-step solvothermal method. The Brunauer−Emmett−Teller analysis shows SnSe with a specific surface area of about 0.3 m 2 g −1 , while RGO−SnSe significantly increases it to 8.44 m 2 g −1 . The photocatalytic kinetics of the RGO−SnSe composite revealed a pseudo-first-order reaction mechanism during the degradation of norfloxacin antibiotics in an aqueous environment. Results indicated that an increase in RGO content in the composites led to enhanced degradation efficiency and apparent quantum yield, reaching maximum values of 90.7 and 11.37%, respectively, at a specific RGO loading of 37 wt %. These values were found to be 3.6 times higher than pure SnSe. However, further augmentation of RGO resulted in a decline in both efficiency and yield. The enhanced catalytic performance can be attributed to the improved synergy between RGO and SnSe. The electrical energy per order was calculated to assess the energy efficiency of the photocatalytic degradation process, yielding a low value of 6.7 kW h m −3 /order for the RGO−SnSe composite with a loading of 0.75 mg/L RGO−SnSe catalyst. The photocatalytic activity of the composite remained nearly unchanged for at least four repeated cycles without any degradation of the catalyst. This outcome underscores the efficacy of the RGO−SnSe composite as an efficient and sustainable technique for antibiotic degradation with a high apparent quantum yield and low energy consumption.

Synthesis of novel AgI/BiOI nanocomposites and their high-efficiency visible-light-driven photocatalytic degradation performance for norfloxacin

Abstract: AgI/BiOI composites are prepared with BiOI nanosheets as the substrate by an in situ ion-exchange process. The AgI/BiOI-1.2 with a Ag/Bi molar ratio of 1.2 demonstrates a Bi5O7I composition and a high photocatalytic performance for NOR degradation.
