The article in the European Journal of Organic Chemistry discusses the use of alumina-supported hydroxyanthraquinones for visible-light photooxidations in batch and continuous flow conditions. The researchers, led by Z. Amara, found that the immobilized catalysts were highly active under blue light irradiation and could oxidize various substrates. By transferring the catalysts to a continuous-flow reactor, they were able to compare productivity with homogeneous conditions, highlighting the potential for sustainability in photocatalytic processes. The study was conducted by a diverse team of researchers, including Yahya Al Ayi, Augustin Pirenam Atakpa, Cylia Arab, Maxime Lancel, and Zacharias Amara. [Extracted from the article]
