N2 - To achieve effective wastewater treatment, a composite photocatalyst consisting of 3D hierarchical flowers globose of BiOI combined with bamboo leaves derived biocarbon (C) was synthesized and used for pollutant degradation. The BiOI/C composite exhibited higher degradation efficiency for methylene blue (MB) compared to pure BiOI (62%) under visible light, with a mass ratio of 2:3. Photo-electrochemical measurements confirmed that the introduction of biocarbon enhanced the separation efficiency of electron-holes in BiOI, attributed to its good electron transmission ability. The narrow band gap (2.51 eV) and improved electronic transmission further enhanced the absorption capacity and facilitated charge carrier separation. The possible photocatalytic mechanism of BiOI/C, involving the generation of active radicals such as ·OH, ·O2- and h+ was discussed based on ESR and trapping experiments. These findings highlight the potential of waste biomass carbon as a valuable resource for wastewater treatment.
