Reduced Graphene Oxide Supported Ag Nanoparticles: An Efficient Catalyst for CO2 Conversion at Ambient Conditions

A highly efficient carboxylative cyclization of propargylic alcohols with CO(2)under atmospheric pressure catalyzed by silver (0) nanoparticles decorated reduced graphene oxide (Ag-rGO) is reported. Ag-rGO was fully characterized by scanning electron microscope spectra (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR) spectra, Raman spectra and X-ray photoelectron spectroscopy (XPS). Notably, Ag-rGO can be also applied to the construction of other value-added chemicals (beta-oxopropylcarbamates and 2-oxazolidinones) from CO(2)at ambient conditions. In addition, Ag-rGO is stable and reusable, which shows the potential for the practical application for CO(2)capture and utilization (CCU).
