This work reports the formation of both solid and hollow lignin micro‐ and nanofibers, at room temperature and without polymer binders, by co‐electrospinning. These fibers, after thermal stabilization, are carbonized to produce hollow and solid carbon nanofibers (see figure) with specific surface areas similar to values found for active carbon.
