Influence of Bròˆnsted Acid Sites on Activated Carbon-Based Catalyst for Acetylene Dimerization
Activated
carbon (AC) has been widely used as a support material
with both tunable acidity and abundant functional groups for solid
acid catalysts in various chemical processes such as acetylene dimerization.
A facile, mild acid modification method that directly activates AC
to generate rich defects and oxygen functional group surface structures
with Bròˆnsted acid sites and an enhanced conductivity is presented
here. Impressively, the catalyst with optimized Bròˆnsted acid
sites and an enhanced dispersion of active components exhibited a
superior acetylene dimerization catalytic activity. Moreover, theoretical
calculations indicated that an increase in hydrogen concentration
could inhibit the formation of coke. This research offered a feasible
potential way to devise and construct a carbon-based solid acid catalyst
with an excellent catalytic performance
