Abstract

•The sea urchin-like nesquehonite assembled by nanorods is prepared.•The 3D spider-web-like hydromagnesite is composed of nanosheets.•SA plays a key role in the synthesis of hierarchically structured HMCs.•SA inhibits the phase transition from nesquehonite to hydromagnesite.•Temperature, Mg2+/HCO3− ratio and pH value affect the crystal phase and morphology.
