The surface chemical binding states of NOx-adsorbed La<sub>2</sub><sub>x</sub>Ba<sub>x</sub>SrCu<sub>2</sub>O<sub>6</sub>_??_ were investigated by X-ray photoelectron spectroscopy (XPS) analysis. The chemical shift of Cu2p XPS peak for LaBaSrCu<sub>2</sub>O<sub>6</sub>_??_indicated the increasing hole concentrations at the level of 02p with NO and NO<sub>2</sub> adsorption. On the other hand, the chemical shift of Cu2p XPS peak for La<sub>1</sub>. <sub>5</sub>Ba<sub>0</sub>. <sub>5</sub>SrCu<sub>2</sub>O<sub>6</sub>_??_indicated the decreasing hole concentrations at the level of 02p with NO adsorption. These results suggest that the Ba content affects the NOx gas-sensing properties of the layered-cuprates.
