Abstract: The present disclosure relates to a degradation method of a perfluoroalkyl substance (PFAS). The degradation method includes the following steps: polymerizing indole to synthesize pind; and mixing synthesized pind with the PFAS to form a mixed solution, and illuminating the formed mixed solution to allow pind to generate hydrated electrons (eaq?) for degrading the PFAS.
