Illuminating immobilised photo catalyst reactor

Photochemical reactor – Illuminating supported photocatalysts

In recent years researchers have demonstrated the efficiency gains produced by undertaking photochemical transformations in continuous-flow systems. Continuous flow systems have been used in developing safe and efficient methods utilizing photosensitizers. Most of this recent published work has focused on the use of homogeneous photocatalysts.
In these pages Vapourtec now presents a unique packed-bed photoreactor system designed for illuminating a fixed bed of an immobilised photocatalyst. This system has the potential to provide access to photocatalyst initiated reactions without the need for further purification. This Vapourtec reactor has been used to demonstrate a wide scope of singlet oxygen, [4+2] cycloadditions, heteroatom oxidations and the reduction of nitro groups.
