Deactivation Mechanism and Regeneration of the CuCl/Activated Carbon Catalyst for Gas-Solid Acetylene Dimerization.

26 The Raman spectra showed an increasing trend of I D / I G value as time went on, which may be interpreted as the increase of carbon deposition or vacancies. 16 Meanwhile, the change of the I D / I G value suggests a larger unordered degree in the acetylene dimerization process. 15 This may be associated with the carbon deposition on the sample surface.
