Research Bremen

ThePOMLab has a long tradition in the synthesis and structural characterization of discrete polyoxometalates (POMs). Their physicochemical properties in areas such as catalysis, magnetism, electrochemistry, and biomedicine are also investigated (partially in collaboration). We are particularly interested in d- and f-block metal-containing heteropolytungstates as well as polyoxo-noble-metalates, in particular polyoxopalladates (POPs). Academic as well as industrial projects are being investigated. Some research highlights are the discovery of (i) polyoxopalladates in 2008 (P₁₃As₈), (ii) polyoxoaurates in 2010 (Au₄As₄₀), and (iii) transition metal-containing derivatives of the wheel-shaped P₈W₄₈ wheel in 2005 (Cu₂₀P₈W₄₈).
