Thermal chemistry of trimethyl acetic acid on TiO2(110)

Article Abstract:

On the basis of temperature-programmed desorption and isothermal reaction mass spectrometry, the thermal surface chemistry of trimethyl acetic acid, (CH3)(sub 3)CCOH, dosed onto a well-characterized single-crystal TiO2(110) surface is described. Deprotonation occurs at or below 300 K to form trimethyl acetate, (CH3)(sub 3)CCOO(super -), and hydroxide, OH(super -).

Thermal and photochemistry of tert-butyl iodide on rutile TiO2(110)

Article Abstract:

Isothermal and temperature programmed desorption mass spectrometry were used for examining the thermal and photochemistry of tert-butyl iodide (t-buI) dosed at 100 K on rutile TiO2(110). Results revealed the occurrence of ultraviolet photochemistry while there were qualitative differences found in the behavior of submonolayers and multilayers.

Trimethyl acetate on TiO2(110): Preparation and anaerobic photolysis

Article Abstract:

The preparation and anaerobic ultraviolet photolysis of trimethyl acetate (TMA) on rutile TiO2(110) are examined with an emphasis on reaction paths. Substrates for photolysis are prepared by dosing trimethyl acetic acid at 100, 300 and 550 K.
