The work represents a toolbox for the design of a highly efficient photocatalytic process for
solar-driven synthesis. The focus is the optimization of photoreactors and photocatalysts. The
described photoreactor design strategy is based on numerical methods mapping radiation
transport and additive manufacturing delivering prototypes. The photocatalyst engineering is
based on suitable photocatalyst support strategies and a method for the determination of the
quantum yield in photoreactions.
