SEM images and schematic illustration of growth process. (A) The schematic illustration of the possible growth process from Ag₂CO₃ particles to porous Ag₂CO₃ nanorods. (B) SEM images of Ag₂CO₃ products prepared with PVP-K30 as the dispersing agent (inset scale bar = 100 nm). (C) SEM images of Ag₂CO₃ products prepared by one-time injection of the NaHCO₃ solution (inset scale bar = 100 nm).
