Bismuth tungstate Bi₂WO₆: a review on structural, photophysical and photocatalytic properties

Abstract

This review paper provides a comprehensive overview of the recent trends in bismuth tungstate (Bi2WO6) research, covering its structural, electrical, photoluminescent, and photocatalytic properties.

Recent advances in nano-fertilizers: synthesis, crop yield impact, and economic analysis

“…Bottom-up methods use chemical techniques to build nanomaterials by combining individual units into larger, more stable structures. 61 This process involves building the material piece by piece through chemical synthesis, self-assembly, and positional assembly. Standard bottom-up Fig.…”

“…The most widely used approaches for the preparation of nanoparticles, which subsequently could be used as nanofertilizers, are chemical reduction by organic and inorganic reducing agents. 61,66 Chemical synthesis approaches such as a polyol, chemical vapor deposition (CVD), chemical precipitation, solgel technique, hydrothermal and solvothermal method are applied to prepare various metal oxides, borides, sulfides, and diverse nanoparticles. 67 The polyol technique is a chemical method of synthesizing nanoparticles.…”

Advances in the optical and electronic properties and applications of bismuth-based semiconductor materials

“…3(g)), strong visible light harvesting ability, non-toxicity, and high chemical stability. 116,117 Its crystal structure belongs to the orthorhombic space group Pca 2(1) 17 and is formed by the superposition of [Bi 2 O 2 ] 2+ and [WO 4 ] 2− layers, 118,119 as depicted in Fig. 2(g).…”

“…121 This kind of electronic structure brings about a broad dispersion of the valence bands, which increases the mobility of photogenerated holes and facilitates the oxidation reaction. 118…”

Recent trends on MIL-Fe metal–organic frameworks: synthesis approaches, structural insights, and applications in organic pollutant adsorption and photocatalytic degradation

“…Adsorption, photocatalysis and advanced oxidation are alternative methods that can remove pollutants. 13,14 Photocatalysis produces only harmless by-products. However, current adsorbents and photocatalysts need to be improved to maximize their potential.…”
