title: sp³ -linked amorphous carbon with sulfonic acid groups as a heterogeneous acid catalyst.
abstract: SO₃H-bearing amorphous carbon prepared from polyvinyl chloride (PVC) is studied as a heterogeneous Brønsted acid catalyst. Sulfonation of partially carbonized PVC produces amorphous carbon consisting of small SO₃H-bearing carbon sheets linked by sp³ -based aliphatic hydrocarbons. This carbon material exhibits much higher catalytic performance in the hydrolysis of cellobiose than conventional heterogeneous Brønsted acid catalysts with SO₃H groups, including SO₃H-bearing amorphous carbon derived from cellulose. This can be attributed to a high density of SO₃H groups and the fast diffusion of reactants and products enabled by a flexible carbon network.
