In this work,we developed a simple strategy to synthesize a carbon material with high nitrogen and rich carbon defects.Our approach polymerized diaminopyridine (DAP) and ammonium persulfate (APS).Following a range of different temperature pyrolysis approaches,the resulting rough surface was shown to exhibit edge defects due to N-doping on graphite carbon.A series of catalysts were evaluated using a variety of characterization techniques and tested for catalytic performance.The catalytic performance of the N-doped carbon material enhanced alongside an increment in carbon defects.The NC-800 catalyst exhibited outstanding catalytic activity and stability in acetylene hydrochlorination (C2H2 GHSV =30 h-1,at 220 ℃,the acetylene conversion rate was 98％),with its stability reaching up to 450 h.Due to NC-800 having a nitrogen content of up to 13.46％,it had the largest specific surface area and a high defect amount,as well as strong C2H2 and HCl adsorption.NC-800 has excellent catalytic activity and stability to reflect its unlimited potential as a carbon material.
