Photosensitization of a Molecular Catalyst by CuInS 2 Nanocrystals with ZnS Shell: Interplay of Electron Transfer Dynamics and Surface Modification
Source abstract
Abstract
A molecular catalyst, Cu(PAP) 2, for the hydrogen evolution reaction (HER) is effectively photosensitized in aqueous medium by bare CuInS 2 nanocrystals (NCs) through ultrafast photoinduced electron transfer (PET). A ZnS shell on the NCs retards PET but enhances HER performance, with turnover numbers (TON) of ca. 18,000 over 25 h. This is rationalized by surface remediation, evident in longer photoluminescence lifetimes and possibly effective retardation of back electron transfer for the core–shell NCs.
