Demonstration of Oil-in-Water Emulsion Separation by 3D-TNTs

(A–D) (A) Experimental setup of vertical deployment, where local magnifications are given in (B–D).

(E) Illustration showing the separation mechanism.

(F) The amount of total organic carbon in filtrates and the corresponding separation efficiency using different emulsions.

(G) Recycling tests of the superhydrophilic foam (Type III) employing octane-in-water emulsion. Each of the data point in (F) and (G) was based on at least three samples.
