Z-scheme interface modification by MnV2O6 for V2O5/g-C3N4 heterostructure towards efficient visible photocatalytic activity

Interface modification by defect engineering for g-C3N4/LaPO4−x nanorods towards efficient CO2 photoreduction

“…The emission peaks for the pure g-C 3 N 4 samples from 440 to 460 nm are quite strong, suggesting a large amount of photogenerated electrons recombine with holes in the HOMO levels of g-C 3 N 4 rapidly. 23,44,45 However, the PL spectrum of g-C 3 N 4 /LaPO 4 is almost the same as pure g-C 3 N 4 . This implies the composition of g-C 3 N 4 and LaPO 4 cannot create a new pathway to separate charge carriers.…”

“…Among them, g-C 3 N 4 attracted increased attention owing to its outstanding physical and chemical properties. 22 g-C 3 N 4 was easily synthesized by calcining N-rich materials, such as urea 23 and melamine. 24 The position of LUMO energy levels is estimated to be at around −1.1 V to −1.3 V ( vs NHE), more negative than the reduction potential of CO 2 /CO.…”

Facile synthesis of PbBiO2X/Ti3C2 MXene composites with efficient visible photocatalytic activity

“…To better evaluate the visible catalytic performance of these photocatalysts, the photocatalytic activity of CT10, BT5, IT5, Degussa P25 and g-C 3 N 4 30 on MO degradation in Fig. S6 (ESI †).…”

Photocatalytic Adsorption Synergistic Degradation of Tetracycline by Z-scheme Bi2WO6/ZIF-8

“…One of the reasons should be ascribed to the improved speci c surface area and surface active sites [26]. Another reason was that the heterojunction formed in the composite could change electron transfer routes and improve electron utilization e ciency, which thus improves the photocatalytic activity [12,27,28].…”
