The process of catalyst is to convert large amount of industrial waste into acids. According to the team, tiny amount of these pincer catalyst repeatedly convert large amount of industrial waste such as glycerol into lactic acid and hydrogen. The process is very rapid and effective so that many industries will use this and most especially biomedical industry will use it for the increase in their magnitude. Researchers at IIT Guwahati have formulated efficient pincer catalytic system that transforms industrial or biomass wastes into valuable chemicals. The discovery of the process can be beneficial dimensionally because it can benefit business as well as environment.

The industry waste is now increasing very rapidly and it increases the co2 emission which is harming our environment and also the creatures. The biomass is increasing day by day and it doesn’t have a lot of space that it can be fit in our living area. According to the team, tiny amounts of these pincer catalysts repeatedly convert large amount of industrial waste such as glycerol into lactic acid and hydrogen. Such catalyst also efficiently converts bioethanol, a low energy density fuel, into high energy density butanol. There are some advantages of using catalyst and it can be useful for the human race in future also you can find the advantages below:

  • Catalysts speed up the rate of reaction, which saves money because the plant doesn't have to operate for as long to produce the same amount of product.
  • Catalysts allow the reaction to work at a much lower temperature. This reduces the energy used up in a reaction which is good for sustainable development.
  • They save industries money.
  • They never get used up in a reaction so once you've got them you can use them over and over again.

Pincer catalyst are complex structured molecules in which an organic moiety holds on tightly to a metal core, much like the claws of a crab which makes it harder and it cannot detach easily if you don’t put any external force. Such an arrangement not only confers stability to the catalyst, but also selectively to bring about the intended transformations. The researchers made a lot of efforts and mind to design this catalyst which can be a game changer for the industries and international organizations. They rationally develop and tested a large library of pincer catalyst to be used for these extreme transformations. The experiment was carried out under environmentally benign conditions without the use of hazardous reagents and solvent. It is a very risky process because it can affect any one and can increase the mutation of cell in any of the individual and so it was developed under a very highly prohibited area. The most efficient pincer catalyst was found to be one that had least crowding around the metal centre. Such an arrangement enabled easy removal of hydrogen from the starting materials, glycerol and ethanol and their selective conversions into lactic acid and butanol, respectively. The future of this discovery is very bright because it can give industries a relevant solution for maintaining waste and creating a productive material.

This is a great discovery that it gets featured in many places and especially in the Royal society of chemistry journals- Chemical Communications and Catalysis Science and Technology. Our computational studies have attributed the unprecedented activity of the pincer catalyst to the minimal crowding present at the metal centre and have enabled good understanding of the electronic and steric factors that control the reactivity.
