Evidence of the photogenerated long‐lived biphenyl radical and a trapped electron in the void space of aluminated nonacidic ZSM‐5 zeolites has been obtained from the time‐resolved UV/Vis absorption, Raman scattering, and EPR spectra. The restoration of the ground states implicates the existence of long‐lived positive holes in the framework.
