Recently we published a review paper in RSC Advances without making proper reference to a review paper published by us in Chinese Journal of Catalysis. To ensure that the scientific record is accurate and up-to-date, we would like to add this review paper as a reference. In addition, we would like to make emphasis in the abstract on what the RSC Advances review adds to the field and how it differs from the one published in Chinese Journal of Catalysis.

Modified abstract:
Solid superbases are substances that possess basic sites with strength stronger than H_ = 26 (with H_ corresponding to the pKa value of the indicator). There have been several review papers on solid superbases. In this mini-review, we summarize the achievements made on solid superbase catalysts in the past two decades, addressing the type of superbases and their catalytic applications. It is pointed out that the majority of reported solid superbases were generated using a single metal oxide as support. Included in the review article are the recent progresses made by our group on solid superbases that are based on composite oxides. Our recent research results open up a new route for the design and synthesis of superbase materials. We emphasize that composite metal oxides and porous materials should be developed as support materials to generate solid superbases of novelty, and predict that this will become the main research area of solid superbases. In addition, efforts should be devoted to clarify how the superbase sites are generated. Finally, the application of this class of solid superbases in the area of catalysis is worthy of investigation.

A reference to the article published in the Chinese Journal of Catalysis should be made on line 29, second paragraph of page 2 at the end of the sentence “There are some review papers on solid bases.^7,13-15”
