This question already has an answer here:

I have a document using the elsarticle with \documentclass[5p]{ elsarticle}. Which is fine for the main document body. However, for an appendix I need a single column page, but have been unable to find out how to do this. Can someone tell me how to do this?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.


So I did not realise that elsarticle is based on article. So what I should have searched for was a solution for the article document class.

The solution is to use \onecolumn as presented in this answer: Single Column Appendix in twocolumn article.
