Efficient charge transfer and exposure of reactive sites represent critical factors in the enhancement of photocatalytic nitrogen fixation. Herein, an atomic-thickness phosphate-doped Bi 2 MoO 6 photocatalyst was fabricated successfully. The introduction of PO 4 3− doping induced lattice distortions within the Mo−O octahedron, resulting in the generation of oxygen vacancies and exposure of Mo sites that served as active centers for nitrogen activation. Additionally, the incorporation of PO 4 3− dopants led to a reduced surface work function of Bi 2 MoO 6 , thereby effectively facilitating carrier migration. Furthermore, there is a notable reduction in carrier transport distance from the bulk to its surface due to the atomic sheet structure. As a consequence, the PO 4 3− doped Bi 2 MoO 6 exhibited a significantly enhanced photocatalytic nitrogen fixation activity compared to the undoped sample. Moreover, PO 4 3− -doped Bi 2 MoO 6 showed improved photocatalytic performance for the reduction of Cr(VI). This work offers valuable theoretical insights for the development of highly efficient photocatalysts.

Converting carbon dioxide (CO2) into high‐value chemicals using solar energy remains a formidable challenge. In this study, the CSC@PM6:IDT6CN‐M:IDT8CN‐M non‐fullerene small‐molecule organic semiconductor is designed with highly efficient electron donor‐acceptor (D‐A) interface for photocatalytic reduction of CO2. Atomic Force Microscope and Transmission Electron Microscope images confirmed the formation of an interpenetrating fibrillar network after combination of donor and acceptor. The CO yield from the CSC@PM6:IDT6CN‐M:IDT8CN‐M reached 1346 µmol g−1 h−1, surpassing those of numerous reported inorganic photocatalysts. The D‐A structure effectively facilitated charge separation to enable electrons transfer from the PM6 to IDT6CN‐M:IDT8CN‐M. Meanwhile, attributing to the dipole moments of the strong intermolecular interactions between IDT6CN‐M and IDT8CN‐M, the intermolecular forces are enhanced, and laminar stacking and π‐π stacking are strengthened, thereby reinforcing energy transfer between acceptor molecules and significantly enhanced charge separation. Moreover, the strong internal electric field in the D‐A interface enhanced the excited state lifetime of PM6:IDT6CN‐M:IDT8CN‐M. In situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) analysis demonstrated that carboxylate (COOH*) is the predominant intermediate during CO2 reduction, and possible pathways of CO2 reduction to CO are deduced. This study presents a novel approach for designing materials with D‐A interface to achieve high photocatalytic activity.
