Incorrect units and space groups have been used in the text and Table 2 when discussing the α-Fe₂O₃ crystal structure. The correct sentence and corrections to Table 2 can be found below:

1) "The α-Fe₂O₃ crystal structure (hematite system) belonging to the crystallographic space group R3C[167] has lattice constants (a,b,c) equal to 5.039 Å, 5.039 Å, and 13.770 Å, respectively, with a ratio of c/a = 2.733 (ICDD/JCPDS PDF-89-0597) using the JADE software (Materials Data) for XRD pattern processing and MDI materials data."

2) In Table 2, the correct units for columns 2, 3 and 4 are Å.

3) In Table 2, the correct space group for Samples 1, 2 and 3 is R3C(167).

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
