In the original publication [1], there was a mistake in Figure 4a as published.
Figure 4.
SEM and TEM CSBGC after pickling with various magnifications SEM (a) CSBGC wrapped by annealed and cooled before ferric element removal SEM (b) CSBGC directly prepared from CS SEM (c) and CSBGC TEM (d).
The corrected corn straw picture and caption description from SEM appears below.
Figure 4.
SEM and TEM of CS and CSBGC after pickling, shown at various magnifications: (a) SEM image of corn straw. (b) SEM image of CSBGC wrapped, annealed, and cooled before ferric element removal. (c) SEM image of CSBGC directly prepared from CS. (d) TEM image of CSBGC.
The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
