A double-layer core–shell photocatalytic coating was engineered on carbon fibers (CFb) derived from bamboo pulp precursors, employing a sequential process involving seed pre-loading, solvothermal treatment, and impregnation. XRD, SEM, SEM-EDS analyses revealed that g-C3N4 Bi2O3 nanosheets were co-assembled the fiber skeleton, 50 nm MoS2 particles successfully loaded, resulting in fabrication of MoS2/g-C3N4/Bi2O3/CFb fibers. UV–vis spectroscopy, transient photocurrent response, EIS tests demonstrated introduction narrow-bandgap visible-light photocatalysts (g-C3N4 MoS2) enhanced light absorption improved separation migration efficiency photogenerated electron hole pairs. Photocatalytic degradation experiments MB showed significantly outperformed g-C3N4/Bi2O3/CFb Bi2O3/CFb, achieving 92% within 60 min. Band structure calculations analysis confirmed formation Z-scheme heterojunctions between Bi2O3, as well Bi2O3. This dual heterojunction endowed with redox capabilities, providing novel strategy for developing efficient materials.
