Removal of Tetracycline Hydrochloride from Water by Visible-Light Photocatalysis Using BiFeO3/BC Materials

et al. 2022

It is widely considered that photocatalysis is an effective and eco-friendly method of dealing with organic pollutants dissolved in water. Nonetheless, photocatalysts still have some drawbacks, such as poor visible-light absorption, easy recombination of photogenerated charge carriers, and limited active sites. In this study, bismuth ferrite coupled with biochar material (BiFeO3/BC) was simply synthesized, and its photocatalysis reactivity was systemically examined under an irradiation of λ > 400 nm. The experimental results showed that under a relatively acidic environment, the removal rate of tetracycline hydrochloride reached 95%. Using a variety of characterization investigations, we analyzed the morphology structure and chemical composition of BiFeO3/BC. In consideration of simple preparation and high respondence toward visible light, further explorations of BiFeO3/BC and its properties and optimized degradation conditions are worthwhile.

“…On the other hand, there will be fast recombination of the photo-generated electron-hole pairs. BiFeO3's photocatalytic performance must be increased to overcome this constraint and boost its photocatalytic potential (Chauhan et al 2021;Gang et al 2021;Humayun et al 2019;Jaffari et al 2019;Jiang et al 2022;Liao et al 2021;Li et al 2013;Ponraj et al 2017;Satar et al 2019;Si et al 2018;Volnistem et al 2020).…”

Box-Behnken experimental design was utilized to model and optimize the photocatalytic removal of methylene blue (MB) using ZnO-BiFeO3 composite under visible light (LED). Three catalysts with different ZnO: BiFeO3 molar ratios (2:1, 1:2, and 1:1) were synthesized successfully using hydrothermal method. The synthesized photocatalysts were characterized by XRD, FESEM, EDX, PL, FTIR, and UV-vis. FESEM showed the uniform distribution of ZnO particles over the surface of bigger BiFeO3 particles. The best photocatalytic activity was obtained by ZnO-BiFeO3 with 2:1 molar ratio. In order to optimize the experimental conditions, four factors of initial MB concentration (5 to 20 mg/L), pH (3 to 12), catalyst dosage (0.5 to 1.25 mg/L) and light intensity (4 to 18 W) were selected as independent input variables. BBD suggested a quadratic polynomial equation to fit the experimental data. Results of ANOVA confirmed the goodness of fit for the suggested model (predicted- and adjusted-R2 0.99). The optimum conditions for maximizing the photocatalytic MB degradation were found to be initial MB concentration of 11 mg/L, pH of 11.7, catalyst dosage of 0.716 mg/L, and light intensity of 11.4 W. Under the optimum conditions, the highest photocatalytic MB degradation of 62.9% was obtained which is in reasonable agreement with the predicted value of 69%.
