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
