Ultra-low Ru-promoted CuCl2 as highly active catalyst for the hydrochlorination of acetylene

Here we report a novel catalyst consisting of 400 ppm Ru and 4.24 wt% Cu supported on carbon nanotubes for the hydrochlorination of acetylene. We observed a synergy between Ru and Cu and obtained a highly active catalyst. The TOF of Cu400Ru/MWCNTs was higher than that of the HgCl2 catalysts.
