Graphical Abstract

Hollow structural materials were fabricated from cuprammonium cellulose composite filaments by fast pyrolysis. The whole process could be completed within 100 s. The formation mechanism is related to the heterogeneous structure of the fibers and the gradient distribution of the metal oxides in the cellulose matrix.

Abstract

A facile method for the fabrication of inorganic hollow materials from cuprammonium cellulose composite filaments based on fast pyrolysis has been developed. Unlike Ostwald ripening, approaches based on the Kirkendall effect, and other template methods, this process yielded hollow materials within 100 s. The heterogeneous structure of the cellulose composite fibers and the gradient distribution of the metal oxides are the main reasons for the formation of the hollow structure. The diameter, wall thickness, and length of the hollow microfibers could be conveniently controlled. With their perfect morphology, these hollow structural materials have great potential for use in various fields.
