Extended Data Fig. 8 | Properties of MnO 2 and MnO 2 -doped silica aerogels.
a–g, X-ray diffraction (a), SEM image (b), HRTEM image and lattice spacing (c),
GC/FID spectra of the toluene degradation shown in Fig. 4 on a MnO 2 –SiO 2
bilayer aerogel (d), SAED of the MnO 2 microspheres (e), and STEM image
(f; g, right-most image) and elemental analysis (g, left three images) of the
MnO 2 distribution in the silica aerogel. h, Energy-dispersive X-ray spectroscopy
(right-most image) of a cross-section of the interface between the silica and
MnO 2 -loaded silica aerogel within the thermal transpiration membrane, and
the element distribution maps (Mn, Si, O; left three images).
