Constructing carbon nanotubes@CuBi2O4/AgBiO3 all solid-state mediated Z-scheme photocatalyst with enhanced photocatalytic activity

摘要

? 2022 Elsevier B.V.A novel CNTs@CuBi2O4/AgBiO3, All-Solid State (ASS) Z-scheme photocatalyst was hydrothermally synthesized to explore visible light photocatalytic performance via methylene blue degradation. The ASS Z-scheme heterojunction exhibited 97.94 of degradation in 60 min in visible light. Besides, the photocatalytic activity of heterojunction remained 89.50 after 10 cycles, signifying high stability and reusability of heterojunction. The presence of CNTs on CuBi2O4/AgBiO3 nanoparticles acted as an electron transfer bridge in-between CuBi2O4 and AgBiO3. The ASS Z-scheme-based photocatalytic mechanism considerably enhanced photo-exciton lifetime, longer stability, increased visible light absorption, and photocatalytic activity of fabricated CNTs@CuBi2O4/AgBiO3.
