Influence of Surface Chemistry of Carbon Nanofibers on the Hydrodechlorination of Chloroform to Olefins

Functionalized carbon nanofibers (CNF) are fascinating materials to be used as supports in Pd-based catalysts for the treatment of waste chloroform (TCM) produce light olefins through catalytic hydrodechlorination (HDC). The CNF were functionalized by HNO3, HCl, and urea. Compared Pd supported on un-treated CNF, all using support showed lower turnover frequency values with higher stability, owing their smaller nanoparticles (NPs). These NPs formed due stronger metal–support interactions promoted concentration surface groups catalysts. Since could hinder hydrogenation paraffins, selectivity increased Moreover, N-doped was successfully catalyst nitrogen functional (pyridinic N pyrrolic N) provide much compared oxygen other catalysts, urea smallest among four leading highest olefins.
