A photocatalyst system consisting of ZnSe quantum dots modified with a thiolated imidazolium capping ligand for visible light-driven reduction aqueous CO<sub>2</sub> to CO is reported without the need metal complex co-catalyst.
The photophysical properties of Cu-deficient Cu0.2In1Sx quantum dots synthesized through a facile aqueous-based procedure have been investigated. Transient absorption experiments were carried out probing in the UV–vis, near-IR, and mid-IR regions, with aim to (i) study (ii) monitor kinetics electron transfer molecular catalyst. When pumping sub-bandgap transitions, negative (bleach) signals observed that spectrally kinetically distinct from those bandgap pump wavelengths. Herein, these...
Systems integrating quantum dots with molecular catalysts are attracting ever more attention, primarily owing to their tunability and notable photocatalytic activity in the context of hydrogen evolution reaction (HER) CO2 reduction (CO2RR). CuInS2 (CIS) (QDs) effective photoreductants, having relatively high-energy conduction bands, but electronic structure defect states often lead poor performance, prompting many researchers employ them a core–shell structure. Molecular cobalt HER...
