Design and Experimental Validation of a Photocatalyst Recommender Based on a Large Language Model
Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.Choosing a photocatalyst for a given reaction can be challenging due to complex mechanisms and multiple parameters that govern the outcome of a photocatalyzed reaction. Herein, we disclose a machine learning (ML) model that can suggest catalysts for a given reaction using an online portal.
