Fig. 4. TA spectra of the (a) CdS–PdxS and (b) CdS icosapods at different delay times with 400 nm excitation, respectively. (c) Comparison of 1Σ exciton bleach recovery kinetics of the CdS–PdxS (at 484 nm) and CdS icosapods (at 480 nm) when excited at 400 nm. (d) Proposed possible photocatalytic mechanism for selective oxidation of biomass-relevant alcohols into corresponding aldehydes integrated with H2 evolution over the CdS–PdxS icosapods under visible-light irradiation.
