Macroporous carbons have recently attracted much attention due to their high accessible surface area and capability of supporting fast mass transport and diffusion. Although ordered macro- and mesoporous carbons are commonly synthesized using templates such as silica and polymer beads, metal-organic frameworks (MOFs) have recently been identified as promising porous carbon precursors ena-bling the template-free synthesis of nanoporous carbons via thermolysis. Herein, we report a template-free synthesis of micro-macroporous carbons having an adamantine-like frame, utilizing surface-selective wet-chemical etching of rhombic dodecahedron ZIF-8 crystals to produce macroporous ZIF-8 with four openings and walls, which was subsequently pseudomorphically converted into the de-sired micro-macroporous nitrogen-doped carbons (mM-NC). Compared to microporous carbons (m-NC), the thus prepared macropore-tuned carbon frames were superior adsorbents of large dyes such as rhodamine B (RhB), congo red (CR), and methylene blue (MB) in terms of both kinetics and thermodynamics.
