Green Nano-catalysts and importance of green reactions in Industry: A Review

A Catalysis is a strategic field of science because it involves new ways of meeting energy and sustainability challenges. In the field of green chemistry, there has been a rapid increase in the use of green Nano-catalysts as well as green conditions during the catalysis of industrially relevant reactions. With the aim to avoid the use of toxic reagent, toxic volatile organic solvents, hazardous or harsh reaction conditions as well as challenging and over time-consuming wasteful separations, greener and environmentally benign catalytic protocols have recently become most popular. For the composition of green Nano catalysts is to synthesizing the Nano catalysts by using green solvents or processing the nanocatalysts so that they are finally diffuse in green solvents. The Nano-sized particles increase the exposed surface area of the highly active component of the catalyst, thereby increasing the contact between reactants and catalyst dramatically and imitate the homogeneous catalysts, Green Nano catalysis generally refers to doing the catalytic reaction in the green solvents and preferably by the use of green nanocatalysts for these reactions. This chapter is focus on green nanocatalysts as well as industrially important green reactions.
