A general approach to electrochemical deposition of high quality free-standing noble metal (Pd, Pt, Au, Ag) sub-micron tubes composed of nanoparticles in polar aprotic solvent

A family of free-standing noble metal (Pd, Pt, Au, Ag) sub-micron tubes composed of nanoparticles (STNs) can be synthesized by a one-step electrochemical route in anhydrous dimethyl sulfoxide (DMSO) solution without addition of any other surfactants.
