Adsorption-induced electronic property changes determine the performance of nanostructured transparent conductive oxides and sensor materials. For the study of O2 adsorption on electron rich In2O3–x nanoparticles we used transmission FT-IR spectroscopy in combination with electron paramagnetic reson...
