Biomorphic synthesis of SnO2 microtubules on cotton fibers

Abstract A simple route for synthesis of biomorphic SnO 2 microtubules, using cotton fibers as templates, has been developed. Cotton fibers were infiltrated with tin alkoxide solution and subsequently sintered at high temperatures to produce the final SnO 2 microtubules. The tubular outer surface of the biomorphic SnO 2 microtubules is covered with a large amount of SnO 2 particles. In addition, the sintering temperatures in the fabrication process are shown to have a great effect on the BET surface area and pore-size distribution.
