One-dimensional bismuth vanadate nanostructures constructed Z-scheme photocatalyst for highly efficient degradation of antibiotics

A Solid‐State Carrier Transport‐Prompted Z‐Scheme BiVO4 Quantum Dots‐Based Photocatalyst for Boosted Photocatalytic Degradation of Antibiotics

“…Recently, we synthesized spindle‐shaped BiVO 4 ‐based nanocomposites by one‐step reaction method. [ 3 ] It was found that the types of surfactants play a critical role in the synthesis of spindle‐shaped BiVO 4 . Herein, we established a Z‐scheme photocatalytic compound with an appropriate bandgap and redox ability by integrating a “synthesis and assembly” approach.…”

“…In the past decade, the extensive use of antibiotics worldwide has continued to surge. In the medical, animal husbandry, and pharmaceutical industries, [1][2][3][4] plenty of antibiotic wastewater has been produced, resulting in a significant decline in natural environment quality. The amount of antibiotic residue in foodstuffs is usually minimal, but it could accumulate in the continuous food chain cycle, which will produce potential or immediate damage to our bodies.…”

“…To increase the surface area and photocatalytic reaction active sites, many researchers have developed a large number of BiVO 4 nanostructures with different morphologies, such as rod-shaped, [3,[17][18][19] sphere-shaped, [20,21] flower-shaped, [22,23] and leaf-shaped structures. [13] However, the crystals of these materials are large, usually in the micrometer range, which limit the improvement of their photocatalytic activity.…”

Bismuth-based nanostructured photocatalysts for the remediation of antibiotics and organic dyes

“…Low-dimensional (0-D and 1-D) nanomaterials have been extensively used in the field of photocatalysis over the past few years due to their distinct optical and electronic characteristics [ 42 , 88 , 106 ]. Simple strain relaxation and short diffusion paths are benefits of 1-D nanostructured materials and are advantageous for the separation of photogenerated carriers [ 102 ].…”

“…Simple strain relaxation and short diffusion paths are benefits of 1-D nanostructured materials and are advantageous for the separation of photogenerated carriers [ 102 ]. 1-D spindle-like BiVO 4 nanostructures with oriented carrier transport, high optical performance, and a short carrier diffusion length, for instance, were prepared by Li and co-workers [ 42 ]. The photodegradation rates of ciprofloxacin and tetracycline were, respectively, 94.8% and 81.1% after 1 h. Additionally, Lin et al [ 122 ] prepared 1-D Bi 2 WO 6 nanofibers with a flower-like morphology by using a hydrothermal process for the degradation of rhodamine B dye.…”
