Corrigendum to “Promotional effects of calcination temperature and H₂O on the catalytic activity of Al-substituted MnAlO catalysts for low-temperature acetone oxidation” [Chemosphere 301 (2022) 134722] (Chemosphere (2022) 301, (S0045653522012152), (10.1016/j.chemosphere.2022.134722))

The authors regret that Fig. 3a₂ has been published erroneously. We misuse the TEM image of Fig. 3a₂ owing to their very similar micromorphology between MnAlO-350 and MnAlO-450. Therefore, the authors would like to replace it with the correct one given below. Meanwhile, this TEM image in the “Graphical Abstract” has also been corrected. In current version, this image can show the complete shape and size of the MnAlO-350 catalyst. In addition, in order to distinguish more clearly and easily between Fig. 3a₁ and Fig. 3b₁, the Fig. 3b₁ is also replaced by another FE-SEM image of MnAlO-450. This does not alter the discussion. The authors confirm that this change does not affect the importance of the scientific findings reported in the paper. The authors would like to apologize for any inconvenience caused.[Formula presented] Fig. 3. FE-SEM and TEM images of prepared catalysts (a_1-3: MnAlO-350, b_1-3: MnAlO-450, c_1-3: MnAlO-550).
