Abstract
An equipment for synthesizing the multi-wall carbon nanotubes by water protected arc method features that a protecting pox with downward opening is arranged for the arc region between anode and cathode. In the beginning stage, the gas generated by arc can expel water from the protecting box to form a gas reaction chamber. Its advantages are less loss of carbon as less water vapour taking part in reaction with electrode, high arc stability, high output and impurity of nanotubes, and low cost.
