Preciously Determining Energy Levels and Screening Extraction Medium to Design Highly Efficient Carriers Transport Pathways for Zn‐CuInS2 Quantum Dots Based H2 Generation Application
Abstract:With the creation of long-lived defect states-related donoracceptor pair (DAP) recombination pathway, the Zn doped CuInS 2 quantum dots (CIZS QDs) sensitized TiO 2 photoelectrode displayed a good photocurrent response ability with a density of 2.7 mA/cm 2 . Further introduction Au nanoparticles (NPs) between CIZS and TiO 2 , and the outermost layer CdS, the photocurrent of CdS-CIZSÀ Au-TiO 2 reached 7.5 mA/cm 2 with an increase of 75% and 175%, respectively. The enhancements both in photo-conversion ability an… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
