Pore genius : Sb 2 Te 3 hexagonal nanoplates can be transformed into 3D porous network‐structured Te plates by the dissolution of Sb 3+ ions induced by tartaric acid (TA), the O 2 ‐assisted oxidation of Te 2− ions to Te 0 , and a subsequent Ostwald ripening process (see picture). These Te plates can be adopted as templates for the synthesis of 3D porous nanothread‐based (or nanotube‐based) metal and metal telluride nanoplates.
