Fig. 9: Structure and electronic state of SiO2-modified InZrOx-Beta.
From: Selective conversion of CO2 to isobutane-enriched C4 alkanes over InZrOx-Beta composite catalyst
a XRD patterns of fresh InZrOx(CP), InZrOx(SCP-4) and InZrOx(SCP-8). b–d In 3d (b), Zr 3d (c) and Si 2p (d) XPS spectra of fresh InZrOx(CP), InZrOx(SCP-4) and InZrOx(SCP-8). e H2-TPR profiles of fresh InZrOx(CP), InZrOx(SCP-4) and InZrOx(SCP-8). f XRD patterns of H-Beta(40) zeolite separated from the spent InZrOx(CP)-Beta(40), InZrOx(SCP-4)-Beta(40) and InZrOx(SCP-8)-Beta(40) composite catalysts (The shadow insert is the enlargement of XRD patterns in the 2θ range of 29–32°). g–i TEM images of the spent H-Beta(40) zeolite separated from InZrOx(CP)-Beta(40) (g), InZrOx(SCP-4)-Beta(40) (h) and InZrOx(SCP-8)-Beta(40) (i) composite catalysts.
