A facile approach to individualize spherically aggregated pristine carbon nanohorns (pr‐CNHs) was established. Specifically, we found that treatment of pr‐CNHs with chlorosulfonic acid generates positively charged polarized species, which disintegrate toward individualized carbon nanohorns (in‐CNHs). Interestingly, the isolated in‐CNHs were revealed to be p‐doped owing to the adsorption of chlorosulfonate units. The findings were confirmed by data derived from high‐resolution transmission electron microscopy imaging, Raman and ultraviolet photoemission spectroscopy, and additionally supported by theoretical calculations and thermogravimetry.
