Figure S1. XRD patterns of fresh Ir/Nb/Ti catalysts (a). Green squares correspond to peaks of Nb2O5. The insert (b) corresponds to the dotted square area of fresh 1Ir/10Nb/Ti catalyst. XRD pattern of after reaction 1Ir/5Nb/Ti catalyst is also presented. Figure S2. (a) Selected area electron diffract...

| Sumario: | Figure S1. XRD patterns of fresh Ir/Nb/Ti catalysts (a). Green squares correspond to peaks of Nb2O5. The insert (b) corresponds to the dotted square area of fresh 1Ir/10Nb/Ti catalyst. XRD pattern of after reaction 1Ir/5Nb/Ti catalyst is also presented. Figure S2. (a) Selected area electron diffraction of TiO2 nanoparticles with 1% Ir content. (b) HRTEM images of TiO2 nanocrystals viewed in the [211] direction, FFT diffractogram is inserted. (c) and (d) size distributions of 55 TiO2 particles and 22 Ir particles randomly selected. Figure S3. Cs-corrected STEM-HAADF. a) Low-magnification image showing some Nb nanoparticles formed. b) Low-magnification image where Nb was not visualized as it still remained highly dispersed as in the original material. c) Atomic-resolution observation of a TiO2 with the same metallic distribution as the material before reaction (with the Ir species on the surface, bright layer). d) Chemical maps obtained from the image shown in (a).
