On the Problem of Comparing Rates or Apparent Quantum Yields in Heterogeneous Photocatalysis

摘要

In a recent essay Maschmeyer and Che proposed a "simple and practical way towards a normalization" of apparent quantum yields for hydrogen photogeneration catalyzed by semiconductor powders. The proposal is based on the well-known observation that with increasing photocatalyst concentration the apparent quantum yield (AQY) increases first linearly before reaching a constant value.
