Hydrogen-bond induced surface core-level shift in isonicotinic acid

Article Abstract:

X-ray photoelectron spectroscopy (XPS) and X-ray absorption spectroscopy (XAS) were used for studying the intermolecular hydrogen-bonding in thick films of isonicotinic acid evaporated onto rutile TiO2(110). The presence of non-hydrogen-bonded nitrogen atoms in the surface layer may be responsible for the origin of the surface core-level shift.

An alternative approach to ascertain the rate-determining steps of TiO2 photoelctrocatalytic reaction by electrochemical impedance spectroscopy

Article Abstract:

The PEC oxidation of sulphosalicyclic acid (SSA) solution in a TiO2 coated electrode reactor system was monitored. It is shown by the results that there were two arc/semicircles under a high electrical bias, and that there was only one arc/semicircle under a low bias, corresponding to the charge-transfer-dominated reaction.

Adsorption and charge-transfer study of bi-isonicotinic acid on in situ-grown anatase TiO2 nanoparticles

Article Abstract:

The adhesion of a monolayer on in situ-grown anatase TiO2 nanoparticles has been examined through an X-ray emission spectroscopy. The study indicates that there is no vital difference in charge-transfer features compared to adsorption on the rutile surface.
