VERFAHREN ZUR HERSTELLUNG EINER ELEKTRODE MIT EINEM SUBSTRAT, AUSGERICHTETEN KOHLENSTOFFNANORÖHREN UND EINEM DURCH OXIDATIVE ABSCHEIDUNG ABGESCHIEDENEN METALLOXID, ELEKTRODE UND VERWENDUNGEN DAVON

摘要

The present invention relates to a method for preparing an electrode comprising a metal substrate, vertically aligned carbon nanotubes and a metal oxide deposited over the entire length of said vertically aligned carbon nanotubes, said method comprising the following consecutive steps: (a) synthesising, on a metal substrate, a mat of vertically aligned carbon nanotubes; (b) electrochemically depositing the metal oxide on said carbon nanotubes from an electrolytic solution comprising at least one precursor of said metal oxide and at least one nitrate, said electrochemical deposition being carried out by a chronopotentiometry technique. The present invention also relates to the electrode thus prepared and to the uses thereof.
