Enhanced photocatalytic activity of TiO2 with acetylene black and persulfate for degradation of tetracycline hydrochloride under visible light

Highly dispersed NiS2 quantum dots as a promising cocatalyst bridged by acetylene black significantly improved the photocatalytic H2 evolution performance of g-C3N4 nanosheets

“…The emission peak intensity of the samples decreased remarkably with the increase in the amounts of NiS 2 , which indicated that the NiS 2 and AB nanoparticles loaded on the surface of the CNs greatly inhibited the recombination of the photoexcited electron–hole pairs, which was favorable to the photocatalytic HER. 61 In addition, the peak of the CNs–AB/NiS 2 was much lower than that of CNs–NiS 2 10 as the PL spectra shows, indicating that AB served as an electron transfer bridge and accelerated the electron transfer from the CNs to the NiS 2 and markedly reduced the recombination rate of the electron–hole pairs. 31 …”

Practice on treating pharmaceutical compounds (antibiotics) present in wastewater using biosorption techniques with different biowaste compounds. A review

“…The presence of TCL in wastewater has created a threat to the aquatic ecosystem and its surrounding environment. The studies on removing this component from waste water has been achieved using many methods like using the photocatalytic activity test with 1% Eu/BiVO 4 and ternary Ag 3 PO 4 /Co‐3(PO 4 )(2)@Ag heterostructure photocatalyst has displayed photodegradation efficiency of 91.4% degradation, 73,74 using pig manure as a precursor exhibits good degradation of 94.8% in persulfate activation, 75 an unique AgI/UiO‐66(NH 2 ) heterojunction was modified in photocatalytic performance to reach a high removal percentage of tetracycline, 76 the removal rate and constant of reaction rate of LZO/rGO‐3 composite was identified as 82.1% by preparing a one‐stepsol–gelmethod, 77 the aid of UVC photolysis (Ultraviolet light photolysis), center dot OH, and SO 4 ‐center dot to degradation tetracycline was calculated as 5.91%, 61.97%, and 28.11% at pH 7.0, 78 a study done with different weight percentage has been done and TiO 2 /AB‐2.5 wt% exhibited the best removal efficiency of 85%l in photocatalysis process, 79 newly designed aluminum hydroxide gel‐coated nanoscale zero‐valent iron (AHG@NZVI) synthesized and used in adsorption process has 98.1% removal 80 . These are some of the efficient methods used in the sorption of tetracycline from the aqueous environment.…”

Efficient under visible catalysts from electrospun flexible Ag2S/TiO2 composite fiber membrane

“…Photocatalytic degradation of antibiotics is efficient, economical, and environmentally friendly compared with other traditional techniques, such as anaerobic digestion, biodegradation, and adsorption. Antibiotics could be converted into compounds which are readily biodegradable or organic molecules with less toxicity, thereby reducing or eliminating their antibacterial activity [6]. Titanium dioxide (TiO 2 ) has better photocatalytic performance compared with other catalysts used under ultraviolet (UV) light irradiation.…”
