Controlled Synthesis and Properties of 3d–4f Metals Co-doped Polyoxometalates-Based Materials

Abstract It is challenging to explore and prepare polyoxometalates-based nanomaterials (PNMs) with controllable morphologies and diversiform components. Herein, 3d–4f metals are introduced into isopolyoxometalates and Anderson-type polyoxometalates, CeCdW12 nanoflower and EuCrMo6 microflaky have bee...
