Synergistic effect of two action sites on a nitrogen-doped carbon catalyst towards acetylene hydrochlorination

Abstract

Whether the reaction pathway is steady or dynamic over the whole life cycle of a catalyst process can facilitate our understanding of its catalytic behavior. Herein, the dynamic reaction pathways of nitrogen-doped carbon catalysts are investigated in acetylene hydrochlorination. When triggered, the reaction follows the LangmuirHinshelwood mechanism with pyrrolic N and pyridinic N as dual active sites. However, pyridinic N is deactivated first, due to the strong adsorption of hydrogen chloride, causing the reaction to further run with pyrrolic N as the single active site and follow the EleyRideal mechanism. This work provides a new promising way to study the catalytic behavior of nitrogen-doped carbon catalysts.
