Operando Characterization of Electrochemistry at the Rutile TiO<sub>2</sub>(110)/0.1 M HCl Interface Using Ambient Pressure XPS
Ambient pressure X-ray photoelectron spectroscopy (AP-XPS) was employed to investigate the effect of applied potential on the interface of TiO<sub>2</sub>(110) with 0.1 M HCl. The study, which involved operando electrochemical characterization, enabled real-time monitoring and analysis of electrochemical processes. There is a significant influence on the interface composition; in particular, the surface Cl<sup>-</sup> surface coverage varies with electrochemical potential. Moreover, there appears to be a reaction of evolved Cl with adventitious carbon to form C-Cl and C-Cl<sub>2</sub> species.
