Influence of Molecular Weight on Structure and Catalytic Characteristics of Ordered Mesoporous Carbon Derived from Lignin
Bio-renewable lignin has been used
as a carbon source for the preparation
of porous carbon materials. Nevertheless, up to now, there are few
studies about the influence of molecular weight of lignin on the structure
and morphology of the ordered mesoporous carbon. Here, we synthesized
the ordered mesoporous carbon derived from different molecular weights
of lignin and Pluronic F127. Fortunately, we found that molecular
weight is an important factor for obtaining highly ordered channels,
high specific surface area, and ordered mesoporous carbon. More importantly,
the narrow well-defined mesoporous channel could exert a spatial restriction
effect to some extent, which can serve as nanoreactors for efficient
reactions and enhance catalytic performance. The highly ordered mesoporous
carbon from lignin is a good candidate for Fischer–Tropsch
