ZnO/CdS Hierarchical Nanospheres for Photoelectrochemical Sensing of Cu2+
Abstract
ZnO/CdS hierarchical nanospheres were prepared for photoelectrochemical selective sensing of Cu 2+ . Hierarchical ZnO nanospheres were first synthesized by the hydrolysis of zinc salt under ultrasound irradiation, and then CdS nanocrystals were selectively grown on the hierarchical ZnO nanospheres. The light scattering of ZnO nanospheres and the heterointerfaces between CdS and ZnO provided significant advantages for enhanced light absorption and charge separation, thus resulting in an improvement in the photocurrent intensity. A photoelectrochemical sensor was developed based on the interaction between Cu 2+ and CdS. The results showed that this sensor has a good selectivity and high sensitivity for Cu 2+ detection.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
