Additive manufacturing of intricate and inherently photocatalytic flow reactor components

A 2,1,3-benzothiadiazole-based photosensitiser has been successfully incorporated into a commercially available 3D printing resin and utilised to fabricate inherently photocatalytic flow reactor components. The freedom of design provided by additive manufacturing enabled the production of photoactiv...

The photo-generated singlet oxygen cleanly converted furoic acid to the γ-lactone, 5-hydroxy-2(5H)-furanone, with a peak space-time yield of 2.34 mmol m−2 h−1 achieved using the Voronoi monolith.
