Fig. 2

a PO production rates of nonmodified TS-1(100) and TS-1(33) catalysts. b PO production rates of modified TS-1(100)-m and TS-1(33)-m catalysts. c UV-Vis diffuse reflectance spectra of silicalite-1, TS-1, and modified TS-1. d Ti K-edge XANES of TiO2 (anatase), TiO2 (rutile), TS-1, and modified TS-1. e Fourier transform magnitude of the Ti K-edge EXAFS signal for TS-1(33)-m. f Wavelet transform of the Ti K-edge EXAFS data of TS-1(33)-m obtained using Morlet’s method with η = 5 and σ = 144,45. Reaction conditions for (a, b): 0.1 M NaPi (pH 11), 45 mg catalyst, gas flow O2:C3H6 = 40:1 (41 sccm total), room temperature, H2O2 supply rate is 24.1 μmol h–1; PO production rates averaged over 4–6 h. Source data are provided as a Source data file.
