Summary: This paper presents a novel method for fabricating free-standing 3D hierarchical porous carbon aerogels from molecularly engineered biomass-derived hydrogels. The regulation of pore structure during in situ mineralization assisted one-step activation graphitization (iMAG) is achieved by the in situ formed flower-like CaCO3 embedded within the hydrogel network. The uniformly distributed minerals act as a hard template, activating agent, and graphitization catalyst, resulting in a robust carbon aerogel with high porosity and excellent electrochemical performance.
