 The study presents a one-step assembly method for stable FeCoMoG-slash-CP using Fe3+, Co2+, H3BTC, and collagen peptide by manipulating complexation effect and solution polarity. Pyrolysis optimization resulted in two nitrogen-doped carbon aerogels with virus-shaped and nanospherical magnetic particles exhibiting excellent electromagnetic wave absorbing and radar stealth performances in FeCo-slash-Fe304-slash-NC and FeCo-slash-NC aerogels.
