WebNov 15, 2024 · By mimicking photosynthesis, the light-driven process that plants use to produce sugars, MIT researchers have designed a new type of photocatalyst that can absorb light and use it to drive a variety of chemical reactions. The new type of catalyst, known as a biohybrid photocatalyst, contains a light-harvesting protein that absorbs light and ... http://lib3.dss.go.th/fulltext/dss_j/2552_57_179_P21_24.pdf
WebPhotosensitizers are light absorbers that alters the course of a photochemical reaction. They usually are catalysts. [1] They can function by many mechanisms, sometimes they donate an electron to the substrate, sometimes they abstract a hydrogen atom from the substrate. At the end of this process, the photosensitizer returns to its ground state ...

Photoredox catalysis is a branch of photochemistry that uses single-electron transfer. Photoredox catalysts are generally drawn from three classes of materials: transition-metal complexes, organic dyes, and semiconductors. While organic photoredox catalysts were dominant throughout the 1990s and early 2000s, soluble transition-metal complexes are more commonly used today.
