FTA: “Our top finding was that extremely small copper nanoclusters are very effective at producing methane," continues Salehi. "This was a significant discovery, indicating that the size and structure of the copper nanoclusters play a crucial role in the reaction's outcome."”
How can that be surprising for “a new catalyst for converting carbon dioxide (CO2) into methane”? Are there any catalysts where their effectiveness doesn’t increase with surface area?
Also, if they make them tiny (“we used copper catalysts with different sizes, from small ones with only 19 atoms to larger ones with 1000 atoms”), how do you make sure you don’t pump out the catalyst with the methane? A filter?
