State‐of‐the‐Art Light‐Driven Hydrogen Generation from Formic Acid and Utilization in Enzymatic Hydrogenations

Year: 2024

Type: article

Abstract: A concept of combining photocatalytically generated hydrogen with green enzymatic reductions is demonstrated. The developed photocatalytic formic acid (FA) dehydrogenation setup based on Pt(x)@TiO 2 shows stable hydrogen generation activity, which is two orders of magnitude higher than reported values of state‐of‐the‐art systems. Mechanistic studies confirm that hydrogen generation proceeds via a photocatalytic pathway, which is entirely different from purely thermal reaction mechanisms previously reported. The viability of the presented approach is demonstrated by the synthesis of value‐added compounds 3‐phenylpropanal and (2 R , 5 S )‐dihydrocarvone at ambient pressure and room temperature, which should be applicable for many other hydrogenation processes, e. g., for the preparation of flavours and fragrance compounds, as well as pharmaceuticals.
