Structural and physicochemical properties of the MoS2 foam/CdS catalyst. a TEM image of MoS2 foam/CdS. b HAADF-STEM image of MoS2 foam/CdS. c Corresponding EDX maps with a red rectangle in HAADF-STEM image of b showing the element distribution of Cd, Mo, and S. d High-resolution HAADF-STEM image of MoS2 foam/CdS. e The k2-weighted EXAFS spectrum of MoS2 foam/CdS versus that of MoS2 sheet/CdS. f Time-resolved photoluminescence (TRPL) spectra of CdS, MoS2 sheet/CdS, and MoS2 foam/CdS. g Schematic illustration of MoS2 foam/CdS for photocatalytic synthesis of EG and H2 from CH3OH. Blue and red lines in e and f represent MoS2 sheet/CdS and MoS2 foam/CdS, respectively. The black line in f represents CdS. Scale bar: a, b 50 nm; d 5 nm
