So that's quite a complex lot of things you have to decide for this.

Well, first of all, it depends on which reaction you're studying, because I would say carbon dioxide conversion to carbon monoxide or methane is definitely one of the, even now, most studied reactions in literature at the moment, definitely, and I guess to methanol too, because you can fiddle around, even though the reaction is the same, you can still fiddle around with the material property, the catalyst.

if you for example wanted to tune and this is something i know very well if you wanted to tune the product to either methane or carbon monoxide then for example you would have if you have a smaller particle size and correspondingly a larger surface area that would for example be that would have a tendency to generate more carbon monoxide and the opposite The contrary is true if you're trying to produce more methane.

And then a way of ensuring that, for example, is to just on the catalyst put less nickel or whatever active metal that can do this reaction if you want to generate more carbon monoxide.

Likewise, if you wanted to generate more methane, then you would have more nickel.

So there is the knowledge there that can do something like this, that can tune the product selectivity.

Of course, then one has to also consider how the material interacts in and of itself.

So how did you come to be solving these sort of problems? Is this something that you were looking for, a particular problem, and this was one you already found? Or did you get into the area because of these sort of problems?
