Surface chemistry of TiCl4 on clean and hydrogen modified W(110): identification of surface intermediates

Sandell, Anders LU ; Andersson, MP ; Jaworowski, AJ ; Roberts, JT and Uvdal, Per LU (2002) In Surface Science 521(3). p.129-138
Abstract
The adsorption and decomposition of titanium tetrachloride (TiCl4) on W(110) were studied with high-resolution core level photoelectron spectroscopy. At least two stable intermediates are formed along the pathway to TiCl4 decomposition: TiCl4(a), which is stable up to 300 K, and TiCl3(a), which is stable up to 500 K. Successive adsorption at 80 K shows that the TiCl4() species forms in the presence of dissociated TiCl4 or hydrogen. This indicates that dissociative sites must be blocked before TiCl4 can adsorb intact.
