Removal of Nitric Oxide through Visible Light Photocatalysis by g‐C3N4 Modified with Perylene Imides
For photocatalytic removal of nitric oxide (NO), two major issues need to be addressed: incomplete oxidation of NO and deactivation of the photocatalyst. In this study, we aimed to solve these two problems by constructing an all-solid-state Z-scheme heterojunction (PI-g-C3N4) consisting of g-C3N4 surface modified with perylene imides (PI). PI-g-C3N4 exhibits significant enhancement in photocata...
متن کاملHierarchical Sheet-on-Sheet ZnIn2S4/g-C3N4 Heterostructure with Highly Efficient Photocatalytic H2 production Based on Photoinduced Interfacial Charge Transfer
We have realized in-situ growth of ultrathin ZnIn2S4 nanosheets on the sheet-like g-C3N4 surfaces to construct a "sheet-on-sheet" hierarchical heterostructure. The as-synthesized ZnIn2S4/g-C3N4 heterojunction nanosheets exhibit remarkably enhancement on the photocatalytic activity for H2 production. This enhanced photoactivity is mainly attributed to the efficient interfacial transfer of photoi...
متن کاملCodeposition of Fe3O4 Nanoparticles Sandwiched Between g-C3N4 and TiO2 Nanosheets: Structure, Characterization and High Photocatalytic Activity for Efficiently Degradation of Dye Pollutants
Novel ternary nanocomposite photocatalysts based on g-C3N4/Fe3O4/TiO2 nanosheet were synthesized using simple solid combustion, hydrothermal and wetness impregnation methods. The g-C3N4 nanosheet (2D)/ Fe3O4/ TiO2 nanosheet (2D) triad-interface nanocomposite arranged in the form of Fe3O4 nanoparticle was sandwiched and well dispersed on the surface between g-C3N4 and TiO2 nanosheets. The synthe...
متن کاملA density functional study on the mechanical properties of metal-free two-dimensional polymer graphitic Carbon-Nitride
Successful synthesis of the stable metal-free two-dimensional polymer graphitic carbon-nitride with remarkable properties has made it as one of the most promising nanostructures in many novel nanodevices, especially photocatalytic ones. Understanding the mechanical properties of nanostructures is of crucial importance. Thus, this study employs density functional theory (DFT) to obtain the mecha...
متن کاملAg2S/g-C3N4 composite photocatalysts for efficient Pt-free hydrogen production. The co-catalyst function of Ag/Ag2S formed by simultaneous photodeposition.
Without Pt as cocatalyst, the photocatalytic hydrogen evolution activity of graphitic carbon nitride (g-C3N4) or even its composite is normally rather low (<1 μmol h(-1)). Exploring Pt-free cocatalysts to substitute precious Pt is of great importance in the photocatalytic field. In the present work, Ag2S-modified g-C3N4 (Ag2S/g-C3N4) composite photocatalysts were prepared via a simple precipita...
