1. A method for synthesizing an intergrown twin Ni2Mo6S6O2/MoS2 two-dimensional nanosheet with exposed (00L) crystal planes, comprising:
using an ion insertion method to restrict Ni ions to be located in a lattice matrix of a Mo-based compound to form an Ni—Mo bonded precursor;
adjusting and controlling a concentration of a sulfur atmosphere to form a dinuclear metal sulfide Ni2Mo6S6O2 and
using a method for growing a single crystal in a limited area to adjust and control a growth direction of Ni2Mo6S6O2, wherein the Ni2Mo6S6O2 is grown, and a single crystal MoS2 is used as a growth template, with the single crystal MoS2 alternately along a crystal plane (110) of the single crystal MoS2, to form a twin Ni2Mo6S6O2/MoS2 two-dimensional nanosheet, wherein the Ni2Mo6S6O2 and the MoS2 are intergrown in the twin Ni2Mo6S6O2/MoS2 two-dimensional nanosheet.
