Comparison of PM Removal Properties of Diverse Samples

(A and B) (A) Proposed capture mechanism of 3D networks of ZIF-8/rGA and (B) long-time PM removal efficiency measurement (error bars represent the standard deviation among three parallel tests). Schematic illustration of fast microparticle collection process when PM passes through various filters with functional co-continuity networks.

(C–E) (C) ZIF-8/rGA (4 mm), (D) 2D polymer nanofiber filter (0.5 mm), and (E) ZIF-8 coating foam (4 mm, most of the ZIF-8 particles decorate on the outermost surface of the foam).

(F and G) (F) Fast adsorption performance of diverse filters and (G) stability performance of ZIF-8/rGA during fast adsorption.
