Carbon Nanocomposites: The Potential Heterogeneous Catalysts for Organic Transformations

摘要

One of the major challenges in chemistry confronted by the chemists is the replacement of conventional homogeneous catalysts by heterogeneous catalysts for the development of green, sustainable and economical chemical processes. Recently, carbon-based nanocomposites have attracted the attention of scientists due to their unique physical and chemical properties such as large surface area and pore volume, chemical inertness, high stability and high electrical conductivity. These NCs have been employed in energy storage, electronic devices, sensors, environmental remediation etc. Owing to the wide availability and low cost, carbon-based materials have been utilized as supports for transition metals and other materials. The carbon-based NCs offer a number of advantages such as high stability, easy recovery, reusability with often minimal leaching of metal ions, and green and sustainable approaches to heterogeneous catalysis for various organic transformations. Hence, they can be used as the substitute for the existing catalyst used for heterogeneous catalysis in industries. In this review, various processing methods for carbon-based nanocomposites and their applications as heterogeneous catalysts for organic transformations like hydrogenation, oxidation, coupling, and multi square component reactions, have been discussed.
