摘要

Abstract

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 (C

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 C

and HCl adsorption. NC-800 has excellent catalytic activity and stability to reflect its unlimited potential as a carbon

material.
