Abstract

The invention discloses a method for directly synthesizing a high conductivity nickel sulfide two-dimension nanosheet array in large scale. The method comprises the first step of synthesizing a xanthogenic acid nickel precursor, and the second step of preparing the nickel sulfide two-dimension nanosheet array, wherein the xanthogenic acid nickel precursor powder is placed into a heating device to be heated to reach the temperature ranging from 160 DEG C to 360 DEG C, the heat preservation is carried out on the xanthogenic acid nickel precursor powder for 10-300 mintues, and then the nickel sulfide two-dimension nanosheet array can be generated on a substrate near the xanthogenic acid nickel precursor. The technological process is simple, parameters are obtained easily and controllably, the repeatability is good, and large-scale industrial production can be achieved. The data result is detailed and accurate, so that the feasibility of the method is fully proven. By means of the technology, the problem that the multi-step processing procedures are commonly complex or the technology period is long or high vacuum equipment is high in cost can be avoided, and an extremely potential candidate scheme is provided for the low-cost and large-scale application of the high conductivity nickel sulfide two-dimension nanosheet array.
