Title : Nano-catalysis & Green Chemistry in Chemical industries
Abstract:
We have to adapt and respond to new challenges more rapidly than ever before. We are learning that we need to innovate solutions and systems that are both locally appropriate and globally relevant.
Discovery of a new drug is a time consuming and very expensive business. Only one out of 5000 compounds may have a chance to be placed on the shelf of a chemist. It has been estimated that it takes 8-10 years of sustained efforts of chemists, pharmacologists and physicians to bring a new product in to the market as a drug. Despite the high cost, efforts are being continuously made to develop new drugs as the annual global sale of drugs crosses US $ 500 billion.
The nano-sized particles increase the exposed surface area of the active component of the catalyst, thereby enhancing the contact between reactants and catalyst dramatically and mimicking the homogeneous catalysts.
The demands for green and sustainable synthetic methods using nano catalysis in the fields of pharmaceutical industries, healthcare and fine chemicals combined with the pressure to produce these substances expeditiously and in an environmentally benign fashion, pose significant challenges to the synthetic chemical community. Green chemistry protects the environment, not by cleaning it up but by inventing new chemistry and new chemical processes that do not pollute. This objective can be achieved through the development using green chemistry techniques like Microwave heating, supercritical carbon dioxide as an important commercial, industrial green solvent, Ionic liquid, Sono chemistry, aqueous hydrogen peroxide for clean oxidation, super critical water oxidation, Biocatalyst in chemical synthesis, Biofuel, Hydrogen fuel etc.
