Selective acetalization of glycerol with acetone over nickel nanoparticles supported on multi-walled carbon nanotubes

The use of multi-walled carbon nanotubes for catalytic applications is acquiring great interest. In this work, heterogeneous catalysts were prepared by incorporating nickel nanoparticles into MWCNTs and were characterized by BET, surface acidity, FTIR, XRD, Raman spectroscopy, and TEM analysis. The...
