Innovative Bismuth Catalyst Enhances CO2 Capture from Industrial Flue Gas
A new photocatalytic system using amino-functionalized bismuth catalysts efficiently converts CO from flue gas into cyclic carbonates. This development is critical for carbon reduction efforts in industrial applications.
The study introduces a novel photocatalytic system, BNOC-TEPAx, which utilizes tetraethylenepentamine (TEPA) grafted onto BiNbOCl to capture CO at 15% concentration from simulated industrial flue gas. Under natural sunlight, this catalyst achieved a production rate of 4.45 mmol·g·h, indicating significant industrial application potential.
