Photocatalysis represents a dynamic and multifaceted area of research, encompassing a wide range of applications such as artificial photosynthesis, photo-biocatalysis, and photoredox catalysis in both solution and supramolecular frameworks. This field also involves using abundant metals and organic catalysts, promoting sustainable synthesis and the degradation of plastics. Our investigation focuses on the potential synergies among the various domains within photocatalysis. We examine the complex interactions among these subfields by emphasizing their distinct challenges and opportunities, il-lustrating how a multidisciplinary approach can foster innovation and contribute to sustainable solutions for the future. For example, artificial photosynthesis has emerged as a promising avenue for generating solar fuels through processes like water splitting and CO₂ reduction. Photocatalysis has revolutionized our methods for assembling molecular building blocks. By merging this dynamic field with other areas of study, we can develop efficient and sustainable practices across a range of technologies. While photocatalysis has reached a level suitable for industrial applications, it is vital to deepen our understanding of its intricate mechanisms to improve reaction quantum yields and support continuous advancement. This field is uniquely positioned to play a significant role in the synthesis, degradation, and recycling of molecules and materials, thereby shaping a sustainable future. To fully leverage the potential of photocatalysis, it is crucial to cultivate a thorough understanding of the processes within various subfields, enabling the most effective management of the use and reuse cycle.
