Enhanced photocatalytic activities of polypyrrole sensitized zinc ferrite/graphitic carbon nitride n-n heterojunction towards ciprofloxacin degradation, hydrogen evolution and antibacterial studies

Advancement towards Antibiotic Remediation: Heterostructure and Composite materials

“…The excellent efficiency could be attributed to polypyrrole loading and double charge transfer mechanism leading to wide light absorption range (200-700 nm) and effective exciton separation respectively. [115] Recently, Acharya et al [116] mentioned a novel Z scheme p-n heterojunction photocatalyst p-type B-doped g-C 3 N 4 with different proportions of n-type BN (BN/BCN) through a simple in-situ growth process and used for around 88 % degradation of TCH under solar light irradiation. The emerged degradation performance was credited to the reduction of electron-hole recombination rate and improved visible light absorption ability for BN/BCN composite.…”

“…Polymer‐derived ZFCN@20PPY showed excellent photocatalytic performance towards CIP degradation (92 %), synthesized via polymerization technique. The excellent efficiency could be attributed to polypyrrole loading and double charge transfer mechanism leading to wide light absorption range (200‐700 nm) and effective exciton separation respectively [115] …”

A Facile Fabrication of ZnFe2O4/Sepiolite Composite with Excellent Photocatalytic Performance on the Removal of Tetracycline Hydrochloride

“…With the rapid expansion of pharmaceutical industry and breeding industry, the pollution of antibiotics and mycotoxins in the water environment has caused great concern. (Li et al, 2018;Das et al, 2020;Sun L. et al, 2020;Zhang et al, 2020). Because it is difficult to be metabolized by humans and animals, a large part of antibiotics are excreted in the form of urine and feces (Song et al, 2019).…”

ZnFe2O4@WO3X/Polypyrrole: An Efficient Ternary Photocatalytic System for Energy and Environmental Application

“…Polymerization reaction takes place just after the addition of ammonium peroxysulphate (APS) in a drop wise manner. The entire reaction was carried out for 5 hrs under 278 k. 3 Finally the precipitate was filtered and washed with distilled water for several times followed by ethanol washing to remove any impurities. The obtained product was dried in an oven at 80°C for 12 h for further use.…”

“…The higher concentration of pollutant will block the photons reaching the surface of photocatalyst and ultimately restricts the photo-degradation process. 3 The efficiency of a photocatalyst will be well determined when it will be tested against industrial or environmental wastewater that contains diversified co-existing ions hampering the degradation process by competing with antibiotic ions for adsorption on the catalyst active sites. The degradation of GMF has been tested in presence of 0.1 M solution of NaCl, KCl, MgCl 2 , CaCl 2 , Na 2 SO 4 , and NaNO 3 to explore the impact of co-existing ions on the efficacy of S7 PZFW15 photocatalyst.…”
