Abstract

Mesoporous carbon nanosheets with high surface areas and large total pore volumes were prepared using tubular halloysite as inorganic matrix and furfuryl alcohol (FA) as carbon precursor by a template-like method. Field emission scanning electron microscope, high-resolution transmission electron microscopy (HRTEM) and nitrogen adsorption analysis were employed to characterize the morphologies and pore structures of the samples. It is found that tunable mesoporous carbons can be obtained by adjusting FA volume concentration. Lowering FA concentration leads to an increase in the BET specific surface area and narrowing of the mesopore size distribution.
