Опубликована: Фев. 6, 2025

The construction of S-scheme heterojunctions with oxygen vacancies (OVs) is an effective strategy to enhance the photocatalytic activity. In this pioneering study, we successfully fabricated Bi12O17Cl2/Bi2S3 abundant OVs (ROV-BOC/BS) using anion exchange method. in situ growth Bi2S3 (BS) nanorods on OVs-rich Bi12O17Cl2 (ROV-BOC) nanosheets resulted interconnected reticulated structure. This structure not only increased specific surface area composite but also established a tightly bound heterojunction, further enhancing content composites. OVs-induced defect levels provide additional channels for photogenerated charge migration. synergy between heterojunction and improved light absorption carrier separation efficiency. Consequently, optimized ROV-BOC/BS-0.1 achieved 95.52% Cr(VI) removal efficiency within 120 min, apparent reaction rate constants 5.39 23.86 times higher than those pure ROV-BOC BS, respectively. investigation provides crucial guidance designing novel photocatalysts OVs.

Ultrathin Cobalt Phthalocyanine/Poly(heptazine imide) Heterojunctions with Co‐N₄ Sites for Improved Photocatalytic CO₂ Reduction and Electron Kinetics

Abstract Poly(heptazine imide) (PHI), an emerging substitute for g‐C 3 N 4 (CN), is a good candidate towards photocatalytic CO 2 reduction, while it still suffers from weak charge separation and low efficiency of electron‐induced reduction reaction. Herein, ultrathin PHI nanosheets are synthesized through molten salt method with CN precursors, subsequently functionalized by assembling cobalt phthalocyanine (CoPc) aggregates via π–π interaction. The optimized CoPc/PHI heterojunction achieves evolution rate 116 µmol g −1 h 97% selectivity, exhibiting ≈23 15‐fold photoactivity improvement compared to PHI, respectively. Experimental theoretical results reveal that the superior performance primarily attributed photogenerated electrons transfer ligand CoPc greatly enhancing separation, then single Co‐N sites efficiently catalyzing conversion. high selectivity derived formation energy barrier *COOH rapid desorption. electron on quantified be 39.7% in situ µs‐transient absorption spectra, much higher than (17.7%), underlining dual role as electron‐accepting platform catalytic site. This work offers feasible strategy designing efficient heterojunctions solar fuel production.
