Correction to: Selective Synthesis of Cyclohexanol Intermediates from Lignin-Based Phenolics and Diaryl Ethers using Hydrogen over Supported Metal Catalysts: A Critical Review

1 Correction to: Catalysis Surveys from Asia https://doi.org/10.1007/s10563-020-09315-3

The authors make the following corrections in the paper:

Figures 1, 5 and 6 are taken from other papers. The relevant papers are cited in the text but the authors would like to cite these in the figures as well.

The revised captions are:

Fig. 1 Structure of lignin with monomeric units (sinapyl, coumaryl, and coniferyl) (image taken from Lee et al. Reference 9)

Fig. 5 GC–MS profile of hydrodeoxygenation or/and hydrogenation of lignin oil to cyclic alcohols using Ni/Nb₂O₅ catalyst in an aqueous medium under H₂ (image taken from Song et al. Reference 79)

Fig. 6 Reported proposed mechanism for the hydrodeoxygenation-hydrogenation of vanillin to methylcyclohexanol using bimetallic CoNi/Al₂O₃ catalyst and H₂ in the presence of isopropanol medium (image taken from Liu et al. Reference 99)

The authors duly acknowledge and highly appreciate original research contributions made by esteemed Lee et al. (Ref. 9), Song et al. (Ref 79), and Liu et al. (Ref. 99). Finally, the authors apologise for any inconvenience caused. The original article has been corrected.
