Researchers Discover More Efficient and Eco-friendly Catalyst

Along with a large variety of industrially and commercially viable products, the chemical industry also produces vast volumes of waste. This is especially true when it comes to the production of fine-chemicals and pharmaceutical, where the volume produced of the required product is, at times, just a small fraction of the amount of waste and other undesirable by-products.

A key factor behind this is the fact that a number of chemical reactions use catalysts that are available in dissolved form. The dissolved catalysts often require a vast amount of effort for separating from the reaction products and solvent for the catalysts to be reused. This problem can be essentially avoided when catalysts are used in the solid form. According to a recent report in the Nature Nanotechnology magazine, researchers have recently developed a solid catalyst for a key chemical reaction.

The catalyst is essentially a molecular lattice formed of nitrogen and carbon atoms; researchers have placed palladium atoms in the cavities of atomic sizes in the lattice. Making tiny particles of this material, the researchers were able to demonstrate its successful use in carrying out the Suzuki reaction—the reaction for which Japanese scientist Akira Suzuki and two associates won the 2010 Nobel Prize in Chemistry—proficiently.

So far, the process has used soluble palladium crystals for commercial applications. Attempts made earlier to use a solid catalyst have mostly resulted in the formation of inefficient and unstable catalysts. However, the new crystal is very stable. Owing to this reason and due to the fact that the new catalyst remains undissolved in the reaction liquid, it can be used more number of times and for longer time periods. Moreover, the catalyst is much more economical and several times more efficient than most conventional catalysts.
