WebFeb 7, 2024 · The photogenerated electrons produced in the MoS 2 will transfer from the MoS 2 flake to ZnO nanowire under the drive of the p–n junction built-in electric field, forming more free electrons in ZnO nanowire (Fig. 3a). Accordingly, MoS 2-on-ZnO heterojunction produces a larger photocurrent under UV light illumination. WebJul 1, 2024 · Here, it is reported that functionalized carbon nitride nanomaterials having many heptazine rings with a positive charge distribution, which can tightly trap photogenerated electrons, efficiently prevent the recombination of photogenerated charges. These stored charges are exceedingly long-lived (up to months) and can drive …
