3%MoOxSy(20°C)/TiO2 normalized Mo K-edge XANES accumulated in (a) transmission and (b) fluorescence throughout the whole operando photocatalytic test. Energy (in eV) of (c) transmission and (d) fluorescence spectra at 0.8 of normalized absorption evolution in time, which is the region of the spectra which appears to evolve the most. (e) CH4 formation rate evolution (in µmol h−1 m−2). Dashed lines are a guide to the eyes to observe trends (not based on mathematical fitting).
