“…A test on the activity of the new synthesized catalyst was carried out, employing the oxidation of anisyl alcohol into panisaldehyde; the maximum yield of p-anisaldehyde was 85% after 30 min of irradiation Remaining on the topic of modified g-CN, using composites can be an approach to overcome some limitations to the use of g-CN itself. Recently, Silva et al reported a work on the performance of a composite photocatalyst based on polyester-supported carbon nitride nanosheets, employed in the selective oxidation of anisyl alcohol [63]. Basically, PES (polyester fiber) was treated with a 1% v/v HNO3 solution to increase the hydrophilicity of the material, without modifying the framework.…”

Within the realm of organic synthesis, photocatalysis has blossomed since the beginning of the last decade. A plethora of classical reactivities, such as selective oxidation of alcohol and amines, redox radical formation of reactive species in situ, and indirect activation of an organic substrate for cycloaddition by EnT, have been revised in a milder and more sustainable fashion via photocatalysis. However, even though the spark of creativity leads scientists to explore new reactions and reactivities, the urgency of replacing the toxic and critical metals that are involved as catalysts has encouraged chemists to find alternatives in the branch of science called organocatalysis. Unfortunately, replacing metal catalysts with organic analogues can be too expensive sometimes; however, this drawback can be solved by the reutilization of the catalyst if it is heterogeneous. The aim of this review is to present the recent works in the field of heterogeneous photocatalysis, applied to organic synthesis, enabled by continuous flow. In detail, among the heterogeneous catalysts, g-CN, polymeric photoactive materials, and supported molecular catalysts have been discussed within their specific sections, rather than focusing on the types of reactions.
