Evaluation of Metal Nanoparticle Synthesis Methods: Green Chemistry and Catalytic Approaches

One of the twelve tenets of Green Chemistry that has shown its worth over and over again is catalysis. When it comes to creating and developing novel chemical processes, "green chemistry" prioritizes hazard reduction as the primary performance metric, with the goal of eliminating or drastically reducing the usage or synthesis of hazardous compounds throughout the whole process. Nanocatalysis, thanks to its high activity, selectivity, and productivity, has emerged as a new scientific discipline in recent years. Nanocatalysts are distinguished from bulk materials by their unusual characteristics, which are the result of structural and electrical changes brought about by their nanoscale size, shape, and extraordinarily high surface area to volume ratio. Electronics and the creation of composite materials are only two examples of the many applications for nanoparticles. Among them, metal nanoparticles stand out owing to their diversified selectivity, surface area, morphological flexibility, and exceptional catalytic activities. In this article, we will provide an evaluation of the different ways that metal nanoparticles may be synthesized, focusing on eco-friendly methods. The industrialization of the enhanced metal nanostructures as effectual catalysts are also covered, and the catalytic effectiveness of the most utilized metal nanoparticles is examined.
