Syntheses and Catalytic Properties of Titanium Nitride Nanoparticles

Syntheses and Catalytic Properties of Titanium Nitride Nanoparticles 

The new method produces TiN powders with surface areas exceeding 200 m g that are otherwise only accessible using a forced flow reactor and a microwave plasma activator in which titanium metal is reacted with N2 in the gas phase [14]. TiN powders with considerably lower specific surface area (Sg 60m g ) were also synthesized using the nitridation of 10-15 nm-sized 

Ti02 particles, the benzene-thermal reaction of TiCLi. and NaN3, chemical vapor reactions, plasma syntheses, or arc-melting [15-20], The optical properties of low-concentrated TiN nanoparticle systems were studied by Quinten [21], Highly dispersed TiN was used as an additive to improve the mechanical properties of titanium carbide-based cermets [22], 

TiN nanoparticles are produced via ammonolysis of TiCl4Ln complexes (L = donor ligand. Table 19.1) in the solid state (Eq. 1) [24]. 

A specific surface area of 100m g corresponds to a particle size of 11 nm (pxiN = 5.39 g cm ) [28] and p. . . owders with Sg=200 m g consist of particles approximately 6 nm in diameter.
