Noble metal nanoparticles for water purification
... Transition metals usually have high melting points leading to a high energy of sublimation. Similarly, owing to filling of the d-band, the transition metal atoms are usually smaller in size (Table 1) and thus have higher ionization energies (Table 1). This explains the lower oxidation potential of tr ...

Coordination complex
In chemistry, a coordination complex or metal complex consists of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents. Many metal-containing compounds, especially those of transition metals, are coordination complexes.
