CdS Nanobelt Based Self-powered Flexible Photodetectors with High Photosensitivty

Asymmetric contacts were used to assemble extremely photosensitive and ultrafast self-powered photodetectors (SPDs) on rigid and polyimide (PI) substrate based on one-dimensional (1D)-CdS nanobelts. The photoresponse characteristics of the constructed...

(002) facets exposed and controllable thickness of CdS nanobelts drive desirable hydrogen-adsorption free energy (△GH) for boosting visible-light photocatalytic performance

In order to obtain the high photocatalytic performance, co-catalysts loading is the most commonly used, which is economically disadvantaged and environmental pollution. Here, we combine the strategy of controllable thickness...

Synthesis and characterization of CdS@ZnO nanoribbon@quantum dot and their enhanced visible-light-driven photocatalytic activities

CdS/ZnO nanoribbon/quantum dot was prepared using thermal decomposition method. Size and distribution of ZnO quantum dots on CdS nanobelt were controlled by concentrations of zinc acetate ethanol solution and thermal decomposition temperature. The structure and optical properties of CdS nanobelts and CdS/ZnO heterostructures are studied by XRD, TEM, PL and Raman scattering and UV–Vis absorption spectra. The photocatalytic performances of CdS nanobelts and CdS/ZnO heterostructures are tested by photocatalytic degradation of RhB aqueous solution under visible light irradiation. Compared with that (83.57%) of CdS nanobelts, the degradation rate (88.66%) of RhB using CdS/ZnO heterostructures as catalyst is significantly improved, which suggests better development prospect in photocatalytic technology and photoelectric device.
