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

Graphical Heterogeneous silver catalysis : Well-defined reduced graphene oxide supported Ag nanoparticles are developed for CO 2 conversion. This catalyst is efficient and reusable for various CO 2 utilization processes. Xiao Zhang, Kai-Hong Chen, Zhi-Hua Zhou, Liang-Nian He* Reduced Graphene Oxide Supported Ag Nanoparticles: An Efficient Catalyst for CO 2 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 (β-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).
