Abstract
In the vast landscape of materials science, bismuth emerges as a compelling element with unique properties and diverse applications. Its intriguing characteristics and advancements in nanotechnology have propelled bismuth-based nanoparticles to the forefront of scientific exploration, promising breakthroughs in various disciplines. This comprehensive review explores diverse methods for synthesizing bismuth-based nanoparticles and nanocomposites, ranging from conventional approaches such as hydrothermal and sol-gel to innovative techniques such as microwave-assisted, microemulsion, and green synthesis. The latter includes unique processes such as laser ablation, chemical vapor deposition methods, combustion as well as surface-mediated and bacterium-based synthesis. Each method's strengths, weaknesses, and specifications are critically examined. Further, the review delves into the adaptable applications of bismuth-based nanoparticles and nanocomposites, emphasizing their antibacterial activity, contribution to photovoltaic studies, potential in supercapacitors, and efficacy in photocatalytic degradations of various organic dyes. The objective of this review is to present a thorough summary of the synthesis methodologies and applications of bismuth-based nanoparticles and nanocomposites, offering valuable insights for researchers and professionals engaged in the burgeoning field of nanoparticles.
