1. An article comprising:
a substrate comprising aluminum metal and/or aluminum alloy;
a catalyst comprising at least one metallic species arranged such that the at least one metallic species is in direct contact with metallic aluminum of the substrate; and
elongated carbon-based nanostructures in direct contact with the catalyst;
wherein the aluminum metal and/or aluminum alloy of the substrate has at least one cross-sectional dimension of at least about 1 mm; and
wherein the at least one metallic species comprises Fe, Co, Ni, Cu, Au, and/or Al.
