Meanwhile, the decomposition behavior of carbon monolith in air is shown in Fig. 5b.The weight loss of C-1000 sample is only 8 wt% at 500 C,mainly resulting from the removal of water absorbed on porous structure as well as the destruction of labile oxygen-containing functional groups in the sample [21]. Therefore, when C-1000 sample is exposed to the flame of alcohol burner, it can keep from combustion and remain inert, suggesting
superior fire-resistant property (see the inset in Fig. 5b and Movie S1).
