The invention discloses a method for separating a two-phase structure in duplex stainless steel, and a reticulated ferrite microporous material, belonging to the technical field of stainless steel, and solving the problem that a single structure cannot be obtained from duplex stainless steel in the prior art. The separation method is that the duplex stainless steel is placed in a mixed solution of copper sulfate and hydrochloric acid for potential anodic polarization to obtain a bimodal polarization curve, and the duplex stainless steel is placed under the potential value corresponding to the dissolution peak with the higher potential value. , Copper sulfate and hydrochloric acid mixed solution for constant potential polarization to obtain the ferrite phase of duplex stainless steel, and the potential value corresponding to the dissolution peak of the duplex stainless steel at the lower potential value to obtain the austenite of the duplex stainless steel Bulk. The above-mentioned separation method can be used to prepare a reticulated ferrite microporous material.
