Ultraflat Excitonic Dispersion in Single Layer G-C3n4

open access: yes
Single-layer graphitic carbon nitride (g-C3N4) is widely regarded as one of the most promising two-dimensional photocatalysts for hydrogen generation via water splitting. Despite its extensive study, limited information is available on its excitonic dispersion and velocity, critical parameters for achieving high charge mobility and efficient ...

Enhancing g‐C3N4 Photocatalytic Activity: K‐Doping and CuO Heterojunction for Selective CO2 Conversion to CH4

open access: yesElectron, EarlyView.
The CuO/K‐g‐C3N4 heterostructure photocatalyst achieves selective CO2 reduction to CH4 (93.03% selectivity) under visible‐light irradiation. K‐doping enhances crystallinity, whereas CuO forms a p‐n heterojunction to promote charge separation and electron transfer.

Dual Ferro‐/Piezo‐Electric Coupling in Two‐Dimensional [Bi2O2]‐Based Layered Structures for Synergistic Harvesting of Mechanical and Solar Energy

open access: yesExploration, EarlyView.
Inter‐plane 2D/2D nanosheet heterojunction based on two piezoelectric [Bi2O2]‐based layered compounds is constructed. Significantly increased piezoelectric properties of BiOBr@Bi5Ti3FeO15 by morphological regulation and interface chemical bonds. Dual‐piezoelectric field can modulate interfacial electric field and the interfacial band bending to ...
