Construction of Bi2WO6/RGO/g-C3N4 2D/2D/2D hybrid Z-scheme heterojunctions with large interfacial contact area for efficient charge separation and high-performance photoreduction of CO2 and H2O into solar fuels

A Cobalt‐Modified Covalent Triazine‐Based Framework as an Efficient Cocatalyst for Visible‐Light‐Driven Photocatalytic CO2 Reduction

“…Both CTF‐1 and Co/CTF‐1 series samples showed broad emission peaks at 450–650 nm, confirming their response to visible light. Besides, the PL emission intensity of Co/CTF‐1 (sample S2) was markedly restrained compared with that of the pristine one, well elaborating the restrained charge carrier recombination rate of the photoinduced electrons and holes . The enhanced charge carrier transfer rate could also further be confirmed by the photoelectrochemical measurements.…”

“…Besides, the PL emission intensity of Co/CTF-1 (sample S2) was markedly restrained compared with that of the pristine one, well elaborating the restrained charge carrier recombination rate of the photoinduced electrons and holes. [51] The enhanced charge carrier transfer rate could also further be confirmed by the photoelectrochemical measurements. As shown in Figure 3c, a remarkably decreased radius was found after the loading of cobalt species into CTF-1, indicating that the recombination of the photogenerated carriers was hindered.…”

Graphene Dispersed Bi2WO6 Nanosheets with Promoted Interfacial Charge Separation for Visible Light Photocatalysis

“…Although composite photocatalysts constructed using graphene and its derivations have been found to exhibit good performance in various photocatalytic reactions, most of these works mainly concern the adjustment of surface nanostructures, morphology and surface area issues, and other factors were seldom considered. Due to their unique layered and flexible properties, graphene can be feasibly constructed on the surface of semiconductors with uniform distribution, beneficial for promoting the interfacial charge separation between graphene and semiconductors . Oleg V. Prezhdo and co‐workers found that the photoinduced electron transfer across the interface of graphene/TiO 2 indeed occurs several times faster than the electron‐phonon energy relaxation, which maybe the reason why graphene‐TiO 2 composites exhibit excellent potential for photovoltaic applications .…”

“…Due to their unique layered and flexible properties, graphene can be feasibly constructed on the surface of semiconductors with uniform distribution, beneficial for promoting the interfacial charge separation between graphene and semiconductors. [24][25][26] Oleg V. Prezhdo and co-workers found that the photoinduced electron transfer across the interface of graphene/TiO 2 indeed occurs several times faster than the electron-phonon energy relaxation, which maybe the reason why graphene-TiO 2 composites exhibit excellent potential for photovoltaic applications. [27] However, only few works have focused on manipulating the interfacial charge transferring using graphene-based materials and furthermore, the intrinsic role that graphene-based materials played is still not clear enough in the composite photocatalysts.…”
