概要:
A helical ruthenium compound with a hexagonal mesostructure templated by 1-dodecanesulfonate assemblies was synthesized by the homogeneous precipitation method using urea. The lengths of the helical particles were between micrometers and several tens of micrometers, and the helical pitches of all the particles were constant between several tens and hundreds of nanometers. TEM observation revealed that these helical particles were either hollow (i.e., helical nanotubes) or solid. The tip of the hollow helical particles was open, and the hollow portion was also helical. A double helical structure was also observed. The helical ruthenium compound was converted into helical porous ruthenium oxide by the calcination at 500 �C or more and helical metallic ruthenium by the H2 treatment of the 300 �C calcined helical ruthenium compound.
