Fixation of CO2 as Carboxylic Acid Precursor by Microcrystalline Cellulose (MCC) Supported Ag NPs: A More Efficient, Sustainable, Biodegradable and Eco-friendly Catalyst

Abstract

Silver Nanoparticles supported on microcrystalline cellulose (Ag NPs@ MCC), an active catalyst has been discovered for the direct carbonylation of terminal alkynes with CO2 in to carboxylic acid at mild and sustainable reaction conditions. The stabilized Ag NPs shows higher distribution with uniform particle size. The catalyst was characterized by PXRD, SEM, TEM, HR-TEM, EDS, EDX, ICP-AES and XPS analysis. Ag NPs@ MCC material were found to be more efficient, shows excellent dispersion in solvents and biodegradable. The solvents effects on carbonylation of terminal alkynes were well studied by experimentally and computationally. Further, the present catalyst can be recyclable up to five catalytic cycles without significant loss in its activity and also applicable for the gram scale carbonylation of terminal alkynes.
