Special Issue Information

Dear Colleagues,

In light of the ongoing advancements in nanoscience and nanotechnology, there has been a surge in interest in low-dimensional nanomaterials, particularly those demonstrating compelling structural and functional attributes. This heightened attention is particularly evident in the domains of photocatalysts and gas sensors.

The nanoscale dimensions of these materials, often approaching quantum limits, endow them with a remarkable surface-to-volume ratio, intricate surface/interface effects, and distinctive physical and chemical properties not observed in their bulk counterparts. Consequently, these characteristics open up expanded horizons for diverse applications. Recognizing the significance of these advances, we seek comprehensive reports on noteworthy developments in low-dimensional nanomaterials classified as 0D, 1D, and 2D, with a particular emphasis on their material, structural, and functional attributes.

To offer clarity, low-dimensional nanomaterials are generally categorized as nanoparticles (0D), nanorods, nanowires, and nanobelts (1D), and atomically thin layered materials (2D). This Special Issue aims to provide a streamlined guide for scientists and engineers engaged in cutting-edge research on low-dimensional nanomaterials for photocatalysts and gas sensors.

We invite contributions covering a spectrum of materials, including, but not limited to, noble metals, metal oxide semiconductors, carbon nanomaterials, metal dichalcogenides, g-C3N4, MXenes, and complex composites. Submissions are encouraged to delve into discussions on the interplay between performance and structure, electronic and chemical properties, as well as surface and interface characteristics within the realm of photocatalysts and gas sensors employing low-dimensional nanomaterials.

Furthermore, we welcome submissions that extend the discourse to applications of photocatalysts and gas sensors based on low-dimensional nanomaterials. These could encompass discussions ranging from the current landscape and existing challenges to future research perspectives.

Your valuable contributions will undoubtedly enrich the scholarly dialogue in our upcoming Special Issue. We look forward to receiving your submissions and appreciate your commitment to advancing the field.

Two-dimensional direct Z-scheme photocatalysts have emerged as highly promising photocatalysts for solar-driven water splitting owing to their effective separation of photogenerated carriers and strong redox abilities. This study focuses on the theoretical prediction of promising Z-scheme photocatalysts for solar-driven water splitting based on M2X/BiOY (M = Ag, Au; X = S, Se; Y = Cl, Br, I) heterojunctions using first-principles calculations. All M2X/BiOY heterojunctions possess staggered band alignments, Z-scheme carrier migration, and suitable band edges for overall water splitting. Optical absorption spectra indicate that these heterojunctions exhibit significantly extended solar absorption in the visible and near-infrared regions. Moreover, the interfacial built-in electric fields of (0.46–0.72 V/Å) point from M2X to BiOY, promote photogenerated carrier separation, and enhance redox overpotentials, thereby improving photocatalytic performance. These results suggest that M2X/BiOY heterojunctions are promising Z-scheme photocatalysts for solar-driven water splitting and are expected to be experimentally prepared and realized in the near future.
