Method for preparation of metal nanowires

A method for the preparation of zero-valent-transition metal nanowires comprising the steps of:

• i) providing a reaction mixture comprising:
• at least one capping agent, at least one transition metal salt, and at least one polar solvent;
• ii) adding the reaction mixture obtained in step (i) to at least one reactor;
• iii) heating the at least one reactor of step (ii) at a temperature between 30 and 300° C. for a period of time between 10 min and 7 days under a pressure of at least 100 KPa in a reactor oven to obtain a suspension comprising zero-valent-transition metal nanowires;
• wherein said at least one reactor comprises a longitudinal axis X-X′ and performs at least one of the following movements:
• a translational movement following a closed-path, and
• a rotational movement around the longitudinal axis X-X′ or around an axis W-W′ parallel to said longitudinal axis X-X′, at a constant frequency between 1 and 100 rpm;
• and
• iv) optionally performing a purification process of the suspension obtained in step (iii) to obtain a purified suspension comprising zero-valent-transition metal nanowires.
