MOF-derived nitrogen-doped porous carbon as metal-free catalysts for acetylene hydrochlorination.

A series of ZIF-derived nitrogen-doped carbon materials were prepared using melamine as the additional nitrogen sources for acetylene hydrochlorination. The results indicated that the optimal complex of Z 4 M 1 exhibits the highest acetylene conversion of 60% under the reaction conditions of 180 °C, C 2 H 2 gas hourly space velocity (GHSV) = 50 h −1 , V HCl /V C2H2 = 1.15, suggesting a promising metal-free catalyst for acetylene hydrochlorination. It is illustrated that the additions of melamine not only make the complex of Z 4 M 1 displays special morphological structure and proper pore structure, but also adjust the relative content ratio of three nitrogen species in ZIF-derived nitrogen-doped carbon materials.
