Adsorption of water on TiC(100): evidence for complex reaction and desorption pathways
Article Abstract:
The interaction of water with the nonpolar TiC(100) face was investigated as a function of surface temperature over the range 98-773 K. Temperature-programmed desorption has been used to monitor the desorption products as a function of coverage while high-resolution electron energy loss spectroscopy was used to probe the nature of adsorbed species as a function of surface temperature. Findings show the presence of both molecularly and dissociatively adsorbed water in the monolayer regime at cryogenic temperatures.

Coordination chemistry of transition metal carbide surfaces: detailed spectroscopic and theoretical investigations of CO adsorption on TiC and VC (100) surfaces
Article Abstract:
Analysis conducted on detailed spectroscopic studies of the interaction of Carbon Monoxide with the (100) surfaces of titanium carbide (TiC) and Vanadium Carbide (VC) is presented to investigate the nature of surface chemical reactions. The results show that the electronic structure clearly plays a dominant role in the surface bonding of the carbides controlling their reactivity with lubricants and reactants with which they come in contact.

Substrate-dependent reactivity of water on metal carbide surfaces
Article Abstract:
Results show that water adsorbs onto titanium carbide and vanadium carbide at molecular level in a dissociative way. Data further indicate that differences in the electronic structures of the metal carbides result in different surface bonding and desorption profiles.
