Reaction-driven formation of anisotropic strains in FeTeSe nanosheets boosts low-concentration nitrate reduction to ammonia

Structural characterizations of catalysts

The formation of reaction-driven anisotropic strains in FeTeSe nanosheets involves three steps (Fig. 1a). Fe(Te_xSe_1−x) is a typical layered material that crystallizes in a tetragonal structure (P4/nmm),…
