A New Blueprint for Cleaner Chemical Synthesis
Researchers have engineered a core-shell photocatalyst to precisely control competing chemical reactions. By creating a confined environment using a metal-organic framework (MOF) core and a covalent organic framework (COF) shell, the system directs electrons to a specific site for efficient NADH synthesis while simultaneously restricting the movement of the product. This spatial and temporal management boosts the production rate by 2.82 mmol g⁻¹ h⁻¹ and reduces unwanted degradation of the valuable product by 63%.
Why it might matter to you:
The principle of using confined environments to separate and protect valuable products from competing degradation pathways offers a powerful design strategy for separation and recovery processes. This approach could inform the development of next-generation functional materials that selectively isolate target compounds in complex mixtures, a core challenge in sustainable resource recovery. It demonstrates how controlling molecular movement within engineered structures can dramatically improve both yield and purity.
