Resolving the Formation Mechanism of Core-Shell Type Polyoxometalates (POMs)

Scientific Achievement

Neutron and x-ray scattering studies resolve the formation mechanism for typical core-shell POMs.

Significance and Impact

POMs are a group of nanoscale metal-oxide molecular clusters with broad applications in catalysts and magnetically/electronically active materials. Understanding their formation mechanism is vital for the design and synthesis of new clusters with tuned physical and chemical properties.
