adsorption of HCl and suppress the reduction of active Au
species by C2H2, resulting in superior activity and stability of
Au/N, S-AC-700 catalyst. Presence of sulfur species on the
carbon surface was considered to be able to inhibit the
formation of undesirable pyridinic N species. Most importantly,
our Au/N, S-AC-700 catalyst has been proved to be a strong
competitor to the commercial Hg/AC catalyst in industrial
acetylene hydrochlorination.

The activated carbon (NORIT ROX 0.8) was first pretreated with 1-ethyl-
3-methylimidazolium thiocynate ([Emim][SCN]), (Lanzhou Green chem
Co., Ltd., 99%) for 12 h. The obtained mixture was then thermally
treated in N2 atmosphere at 500, 600 and 700 °C to obtain N, S-AC-500,
N, S-AC-600 and N, S-AC-700, respectively. As a representative, the
obtained N, S-AC-700 sample and HAuCl4 was dissolved in deionized
water. Subsequently, the impregnated sample was laid overnight.
Finally, the sample was dried at 110 °C for 16 h under nitrogen flow to
obtain the catalyst, labeled as Au/N, S-AC-700 with a nominal Au
loading of 1 wt.%.

The catalytic performance was monitered in a fixed-bed micro-reactor
(10 mm diameter). After the catalyst was loaded into the reactor, the
reactor was heated up to the reaction temperature at a ramp rate of
10 °C /min and held for 30 min under nitrogen atmosphere. Then, the
C2H2/HCl mixed gas was fed into the reactor under ambient pressure.
The effluent gas mixture from the reactor was flew through a bubbler
containing aqueous sodium hydroxide solution to remove any unreacted
hydrogen chloride and the resulting gas was then analyzed by gas
chromatography to calculate the acetylene conversion and VCM
selectivity.

Characterization of catalysts
Scanning electron microscopy (SEM) morphology was evaluated with a
Philips XL-30 scanning electron microscope. Transmission electron
microscopy (TEM) analysis was performed on a Tecnai G2 F30 S-Twin,
operating at an acceleration voltage of 300 kV. Nitrogen
adsorption/desorption isotherms was performed using a Micromeritics
ASAP 2020 instrument. X-ray diffraction (XRD) measurements were
obtained using a PANalytical-X'Pert PRO generator with Cu Kα radiation
(λ= 0.1541 nm). X-ray photoelectron spectroscopy (XPS) was
