Peroxide production by porphyrins

Photocatalytic hydrogen peroxide synthesis is a green approach to produce this widely-used chemical and potential energy carrier, yet performance is often poor. A porphyrin-based photocatalyst is now shown to produce hydrogen peroxide by an unusual mechanism involving both photoexcited electrons and holes with promising efficiency.

Automated summary

Photocatalytic hydrogen peroxide synthesis is a green method to produce this commonly used chemical and potential energy carrier, but its performance is often inadequate. A porphyrin-based photocatalyst has been demonstrated to generate hydrogen peroxide efficiently through an unconventional mechanism involving both photoexcited electrons and holes.
