Solution‐Phase Synthesis and High Photocatalytic Activity of Wurtzite ZnSe Ultrathin Nanobelts: A General Route to 1D Semiconductor Nanostructured Materials

Abstract

A general and facile synthetic route has been developed to prepare 1D semiconductor nanomaterials in a binary solution of distilled water and ethanol amine. The influence of the volume ratio of mixed solvents and reaction temperature on the yield and final morphology of products was investigated. Significantly, this is the first time that wurtzite ZnSe ultrathin nanobelts have been synthesized in solution. It has been confirmed that the photocatalytic activity of ZnSe nanobelts in the photodegradation of the fuchsine acid is higher than that of TiO(2) nanoparticles. The present work shows that the solvothermal route is facile, cheap, and versatile. Thus, it is very easy to realize scaled-up production, and brings new light on the synthesis and self-assembly of functional materials.

Review of one-dimensional and two-dimensional nanostructured materials for hydrogen generation

“…2D nanostructures such as nanobelts (NBs), [199][200][201] NSs, [202][203][204] nanoplates, [205][206][207] nanolayers, 208,209 nanoribbons, 115,210 and nanoleaves 211 are also efficient for the production of H 2 . The transfer of charge carriers to the surface takes place in a similar manner to 1D structures and helps to enhance performance.…”

Synthesis of Semiconducting Functional Materials in Solution: From II‐VI Semiconductor to Inorganic–Organic Hybrid Semiconductor Nanomaterials

“…[113] Moreover, wurtzite CdS and CdSe nanostructures with complex morphologies such as urchin-like CdS nanoflowers, branched nanowires and fractal nanotrees, which exhibit effective photocatalytic performance in the photodegradation of acid fuchsine at ambient temperature, can also be synthesized via a facile solvothermal approach in a similar mixed solution. [114] Furthermore, this solvothermal reaction in a mixed binary solvent system can be extended for the synthesis of well-defined wurtzite ZnSe ultrathin nanobelts, [115] wurtzite ZnS architectural structures, [116] and various CdS nanostructures.

High‐Performance Blue/Ultraviolet‐Light‐Sensitive ZnSe‐Nanobelt Photodetectors

“…[9][10][11][12] Zinc selenide (ZnSe), an important II-VI compound semiconductor with a wide direct bandgap of $2.70 eV ($460 nm) at room temperature (RT), has long been considered as a prospective material for optoelectronic devices. [13][14][15] ZnSe is used in II-VI light-emitting diodes (LEDs) and diode lasers working in the blue-light region. As compared to Si and GaAs, ZnSe is more sensitive to blue/UV light.…”
