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 degrees C, C2H2 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.
