Abstract
The surface modification of various materials with small particles of sizes down to the nano scale is technologically very important. In this article we report about the use of metal-rich niobium halide cluster compounds to modify surfaces. In a deposition and subsequent decomposition procedure, small metallic particles of the refractory high-melting metal niobium are produced. These particles offer several potential areas of applications, like in heterogeneous catalysis or as hard-surface coating materials. Overall, a new, easy-to-use method for surface modifications is described.
