    Densely assembled nanorods consist of the nanoparticles of rutile and those of anatase have been fabricated successfully by a heating-sol-gel template process, respectively. The size of nanorods varies as a diameter of 100-300nm and a length of several micrometers, which are controllable by the pore size of the template. The similarities and/or differences of the fabricated process and microstructure for rutile and anatase nanorods were discussed. TEM image revealed that anatase nanorods are the aggregates of many indistinct polygonal nanoparticles up to ∼10nm in diameter, while rutile nanorods are the aggregates of irregular octagon and/or hexagon nanoparticles in 10-30nm diameter. XRD, ED and HRTEM lattice image confirmed the nanorods fabricated by the heating-sol-gel process are well assembled by many individual nanoparticles. The nanoparticles in rutile nanorods were larger than those in anatase nanorods possibly due to the different heat-treatment procedure.
