Abstract

Ruthenium (Ru) was supported on either interior or exterior surface of carbon nanotubes (CNTs) to study the effects of catalytic site positions on the conversion of cellobiose. The catalyst with Ru particles dispersed on the interior CNT surface (Ru-in-CNTs) exhibits higher catalytic activity and better stability than that of Ru particles supported on the exterior surface. It was found that the encapsulation of Ru particles inside the CNT channels improves the reducibility of Ru and decreases the leaching of catalytic sites, which could be the reasons behind the enhanced catalytic performance of Ru-in-CNTs catalyst.
