Direct evidence for the reaction pathway of methane and hydrogen sulfide reforming (H2SMR) was obtained by in situ diffuse reflectance infrared Fourier-transform spectroscopy (DRIFTS). [Display omitted] •CH3S* as key intermediate in H2SMR converts CH4/H2S to H2/CS2.•H2SMR’s synergistic effects set i...
