Fig. 5: In-situ XANES, EXAFS, and CO-DRIFTS investigations over Pt/In-ZSM-5 catalysts.
From: Confining platinum clusters in indium-modified ZSM-5 zeolite to promote propane dehydrogenation
a In-situ XANES spectra of In K-edge and (b) in-situ Fourier-transformed EXAFS spectra over PtIn-based catalysts. In foil and In2O3 were also measured as standards for reference. c In-situ XANES spectra of Pt L3-edge and d in-situ Fourier-transformed EXAFS spectra over PtIn-based catalysts. e In-situ XANES spectra of Pt L3-edge over xPt/In-ZSM-5 catalysts. The spectra were collected in the presence of 20% H2/He at 550 °C. f CO-DRIFTS of xPt/In-ZSM-5 with different Pt loadings. The catalysts were reduced at 550 °C and then cooled down to room temperature in He gas before CO adsorption.
