Metal-organic framework‑derived carbon‑based composites for electromagnetic wave absorption: Dimension design and morphology regulation

•The recent progress of dimension design and morphology regulation of MOF-derived carbon-based MAMs has been summarized.•The effectiveness of dimension and morphology design has been demonstrated in tuning the EMW absorption performance of MAMs.•The fundamental dimension-morphology-function relationship is discussed based on the selected representative examples.•The facing challenges and future perspective of dimension and morphology engineering for MAMs are rationally proposed.
