Synchronizing periodic excitations of photocatalysts with a Michelson interferometer on operando FT-IR spectroscopy, researchers succeeded in observing and identifying the reactive electron species for photocatalytic hydrogen evolution. In contrast to the traditional belief, this study demonstrates that not the free electrons in metal cocatalysts but the electrons trapped in the periphery of cocatalysts directly contribute to the photocatalysis.
