AbstractThe catalyst (CDBQ) that was prepared from beta-cydodextrin (beta-CD) and 2,5-dihydroxy-1,4-benzoquinone (2,5-DBQ) achieved the cavity-confined acceleration of iron cycle under visible irradiation. The semi-quinone-like (SQ) radical was generated from photoexcitation of 2,5-DBQ within the beta-CD's cavity. The SQ radical as an electron donor could coordinate with iron ions, and thus 2,5-DBQ shuttled one electron between Fe3+ and Fe2+ via Fe-dihydroxybenzoquinone complex process. In Fenton reactions, CDBQ greatly increased the HO center dot yield, and thus significantly accelerated the degradation of dyes. The cavity-confined acceleration of iron cycle has promising applications in photo-Fenton system for the efficient decontamination for wastewater. (C) 2015 Elsevier B.V.
