Editorial: Novel Technologies for Sustainable and Energy-efficient Flow Photochemistry

Due to the development of novel light-sources, methodologies and technologies, photochemistry has seen a remarkable renaissance in academia and industry. Many photochemical investigations are now routinely performed under continuous-flow conditions in purpose-designed reactors. Successful examples of pre-industrial applications have subsequently been developed and realized. Likewise, photocalytic materials can be easily incorporated into reactor channels, thus further advancing the potential of flow-photochemistry. This Research Topic comprises of four submissions and highlights recent achievements in photochemical research
