Electrospun BiOCl/Bi₂Ti₂O₇ Nanorod Heterostructures with Enhanced Solar Light Efficiency in the Photocatalytic Degradation of Tetracycline Hydrochloride

Abstract

Bismuth titanates (BTs) can be fabricated by electrospinning combined with calcination at different temperatures. BiOCl/Bi2Ti2O7 nanorod heterostructures were obtained at 500 °C. They possess excellent photocatalytic efficiency and stability for tetracycline hydrochloride (TC‐HCl) degradation under simulated solar light. The excellent catalytic activity is predominantly attributed to the heterostructure between BiOCl and Bi2Ti2O7, which accelerates the separation of photogenerated carriers while the narrow band gap of Bi2Ti2O7 enhances solar energy utilization. On the basis of energy band engineering, scavenger tests, and LC‐HRMS analysis, a possible degradation pathway of TC‐HCl and photocatalytic mechanism were proposed. Our work can predict a facile route for achieving high photocatalytic performance of Bi2Ti2O7‐based materials in the application of TC‐HCl degradation.

Investigation of the Kinetics and Reaction Mechanism for Photodegradation Tetracycline Antibiotics over Sulfur-Doped Bi2WO6-x/ZnIn2S4 Direct Z-Scheme Heterojunction

“…For instance, tetracycline hydrochloride (TCH), as one of the main components of pharmaceutical wastewater, is usually chemically stable and hardly removed by conventional biochemical and physical measures. It can bring about a series of environmental concerns such as causing the formation of resistant microorganisms and upsetting the natural balance [ 1 , 2 , 3 , 4 ]. To mitigate the threats and promote the sustainable and rapid development of industry, it is an emergency to exploit novel technologies aimed at the purification of industrial wastewater.…”

Novel SiO2 nanoparticle-decorated BiOCl nanosheets exhibiting high photocatalytic performances for the removal of organic pollutants

“…Therefore, in the past few decades, in order to overcome these drawbacks, much efforts have been devoted to designing and fabricating highly efficient photocatalysts with novel structures [14][15][16][17][18][19][20][21]. Among the numerous photocatalysts, Bi-based photocatalytic materials, e.g., Bi2O3 [22,23], Bi2S3 [24,25], Bi2WO6 [26][27][28], bismuth oxyhalide (BiOX, X = Cl, Br, and I) [29][30][31][32][33][34], and BiPO4 [35], have been given much importance. BiOCl is a white-colored ecofriendly semiconductor that exhibits an anisotropic layered structure.…”
