A red‐light‐driven photocatalytic hydrogen production system was constructed by combining TTA‐based upconversion micelles with semiconductor Cd 0.5 Zn 0.5 S. Micelles upconvert red photons to cyan photons, which were subsequently absorbed by Cd 0.5 Zn 0.5 S to reduce protons to hydrogen gas. This strategy is beneficial for the solar energy utilization efficiency of the artificial photocatalyst system by increasing the light‐harvesting capability of low energy photons.
