Abstract
The development of an active and competent catalyst for the conversion of carbon dioxide (CO2) to value added-chemicals at low pressure and temperature have great importance in the field of industrial chemical production as well as in tackling global warming. In this report, nitridated dendritic fibrous nano-silica (N-DFNS) as highly porous and stable nano-material have been synthesized by using ammonolysis reaction at various temperature ranging from 500–800 °C and used as heterogeneous catalysts in combination with TBAI for the synthesis of cyclic carbonates from CO2 and epoxide. The presence of high surface area balanced acid-base bi-functionalities generated on silica due to ammonolysis offered high activity towards the synthesis of cyclic carbonates at the atmospheric pressure with excellent recyclability.
