    • The SWNTs were purified using a protocol based on Chiang et al.'s work (25). The process involved soft-baking followed by HCl extraction of the metal catalyst. During neutralization of the acid, the nanotube slurry was exchanged multiple times with hexanes in a separation flask. The SWNTs were found to readily move to the hexane layer, leaving aqueous HCl with extracted metal catalyst that was easily drained off. The purified SWNTs possessed less than 1.2 atom % residual metal catalyst, as determined by thermogravimetric analysis. The resulting purified material was a light porous powder with high surface area that could be easily handled (Fig. 1A).

    • A Renishaw MicroRaman System 1000 with a 780-nm diode laser was used to collect Raman spectra. A multiangle diffractometer equipped with a Cu rotating anode, double-focusing optics, evacuated flight path, and two-dimensional wire detector was used for XRD measurements.
