An overview of bismuth tungstate-based catalysts in various organic transformations

Abstract

Bismuth tungstate (Bi₂WO₆) has received extensive research in a numerous area, including degradation, CO₂ reduction, organic transformations, etc. Due to their wide range of applications, the discovery and development of effective, environmentally safe, gentle, and affordable techniques for the synthesis of bismuth tungstate are critical in organic transformations. There have been reports on variety of multicomponent reactions employing the heterogeneous catalysts Bi₂O₃, BiVO₄, and as well Bi₂WO₆ nanoparticle. Among other materials, Bi₂WO₆ nanoparticles are perceived for their high reactivity at ambient temperature in an aquatic medium. The main objective of this study is to emphasize the mechanistic considerations, scope, benefits, and limits of recent catalytic improvements in the process of oxidation and other reactions. Consequently, the use of Bi₂WO₆ catalyst offers many advantages, including high yields, an ecologically friendly process, quick reaction times, and a straightforward work-up technique. It has been created to use a Bi₂WO₆ catalyst in an aqueous medium in a versatile, simple, one-pot, multi-component technique. This process offers easy-to-find, inexpensive reagents, quick reaction times, great yields, and high atom economy. In this review, we have elaborated how Bi₂WO₆ nanomaterials can be employed as effective and reusable catalysts for organic transformation.
