Abstract
Carbon nanofibers (CNFs) were functionalized with aryl sulfonic
acid groups using in situ diazonium coupling. The use of diazonium
coupling yielded an acidic carbon material, in which the
introduced acidic groups are readily accessible to the triglyceride
substrate. The material is an efficient catalyst for the transesterification
of triolein and methanol, outperforming conventional
sulfonated carbons in both stability and activity per acid
site. Upon comparing CNFs with varying degrees of functionalization,
a linear correlation between sulfonic acid sites and catalytic
performance was found.
