Ann: Halloysite Nanotechnology Breakthroughs for Natural Nanotech, page-133

I think your explanation is good in itself as it explains things well for people seeking an understanding of why, including the benefit on CO2 carbon cost. Earlier in this thread, I posted a link to an article that sort to explain the process as well. I think it is an ok explanation:

A key is temperature, which the Ann itself also alludes to, and just for yourselves this article is interesting in itself, one I found but I need to set up an account to buy it, as the lower temperature aids higher carbon capture - it is why the Ann itself talks about temperature but doesn't specify why and it is about ADN's deposits btw- https://www.sciencedirect.com/science/article/abs/pii/S1387181118305687?via%3Dihub.

All IMO
