摘要

A type of titanium precursor, H-exchanged titanate nanobelts, was used to prepare nanosized anatase titanium dioxide (TiO_2) with various morphologies by hydrothermal method. Nanorods, nanobelts, nano-polyhe-drons and nanoparticles were successfully synthesized. We found that CTAB and EDTA-4Na~+ play critical roles in synthesizing the nanorods and nano-polyhedrons. All the samples exhibit rapid response and recovery time to etha-nol, but Nanorods, nanobelts and nano-polyhedrons show lager response than nanoparticles.
