Applications of bismuth-based nanoparticles for the removal of pollutants in wastewater: a review

Abstract

This review discusses the characteristics and synthesis methods of Bi-based NPs. It delves into the removal efficiency in wastewater, emphasizing traditional/emerging strategies to enhance the performance, mechanisms, toxicology, and challenges.

Improving built-in electric fields for effective photocatalytic activity in the rationally designed electron transfer pathway of TiO2@MoS2/Bi2S3

“…This can enhance the charge transfer and extend the absorptive range across the broad solar spectrum. [9][10][11][12] In an effort to exploit noble-metal-free catalysts to promote the photocatalytic performance, transition metal dichalcogenides (TMDs) have garnered signicant attention. 13 Notably, MoS 2 , a typical two-dimensional layered structure metal sulde, displays numerous superior properties such as excellent physicochemical, optoelectronic properties and electrical conductivity in the layer.…”

Nanoarchitechtonic Marvels: Pioneering One-Pot Synthesis of Bi2WO6 Nanostructures for Breakthrough in Symmetric Supercapacitor Innovation

“…Within the orthorhombic crystal structure of BWO-600, layers of WO 6 octahedra and corner-sharing WO 6 octahedral layers are situated between Bi 2 O 2 2+ layers . Given the strong belief that morphology and characteristics are closely related, numerous efforts have been made to customize the particle morphology according to the intended applications, including modifications to synthesis conditions and procedures. , To make bi-based materials, a range of methods such as hydrothermal, electrospinning, spin coating, solid-state reaction, ultrasonic spray pyrolysis, and pulsed laser deposition are typically employed. − All of these methods have their own set of advantages and disadvantages. The UAS approach was used in this work to synthesize BWO-600, yielding highly crystalline products with a uniform size distribution and fast reaction time.…”
