1. O 2 -with soft oxidizing capacity by electron transfer processes [56] , solving the bottleneck problem of poor HMF oxidation efficiency. By analyzing the above experimental results, a credible mechanism was proposed to illustrate the photo-oxidation of HMF by 1wt%PDI/ZIS. Owing the matching band structure, the photo-generated e -and h + separated efficiently at the SA-PDI and ZnIn 2 S 4 interface, respectively. Then, the photo-generated electron migrated from ZnIn 2 S 4 (CB) to SA-PDI (LUMO), and O 2 adsorbed on the surface of SA-PDI capture electrons and convert to superoxide-radicals. At the same time, HMF is preliminarily oxidized to active-intermediates by the timely photo-generated holes. Afterwards, the formed �O 2 -will oxidize the carbon-centered radicals into the target DFF products on 1wt%PDI/ZIS (Figure 5e);As we predicted
