Abstract:
... Photoelectrochemical (PEC) detection is a widely used detection method that uses light to stimulate and photocurrent signals to detect the target. Due to the disengagement of the excitation unit and the detection unit, the PEC background signal is reduced, and the detection sensitivity is improved. In this work, we report the first demonstration of PEC detection for microfluidic cloth-based analyt ...

Abstract:
... Cadmium sulfide (CdS) is an attractive sulfide semiconductor due to its strong visible light response ability and suitable redox potential, resulting in unique photocatalytic performances. However, the high recombination rate of photoinduced e–/h⁺ pairs and easy photocorrosion of pristine CdS severely limit its application. In this work, a coating layer of graphitic carbon was encapsulated on the ...

However, limited by the extremely low solubility of In₂S₃, it is difficult to increase the In doping contents and inhibit the band energy-level regulation for CdS through the traditional CBD process. In this work, we perform a novel CBD method to prepare an indium-d ...
