Abstract
Halide ions (X−) as cheap and abundant electron donors are oxidized with simulated sunlight in a photocatalytic reaction based on robust antimony porphyrins acting as red-light harvesting multielectron transfer sensitizers. Besides halogen formation (X2/X3−) this solar energy storing process under certain conditions also accumulates hydrogen peroxide (H2O2) as a second energy-rich compound.
