Figure 2

Scanning electron microscopy images for (a) GO@sponge and USTC-6@GO@sponge with (b) small and (c) large USTC-6 particles. The insets in (a) and (b) are enlarged details for the respective microstructures, whereas the inset in (c) shows a photograph of the macroscopic USTC-6@GO@sponge. (d–f) Photographs showing the non-selective adsorption behavior of GO@sponge for gasoline (dyed red) and water. (e) Top and (f) side view for GO@sponge and the liquid mixture. (g–i) Photographs showing gasoline uptake by USTC-6@GO@sponge and subsequent squeezing to recover the gasoline. (j) The adsorption efficiency of USTC-6@GO@sponge for diverse oils and organic solvents.
