Adsorption and Conversion of Ethyl Mercaptan on the Surface of <scp>Ag‐Mn</scp> / <scp> NS‐HNbMoO ₆ </scp>

The composite photocatalyst Ag-Mn/NS-HNbMoO6 was prepared by exfoliation-recombination method. The dispersed state, band structure and charge separation behavior were analyzed by powder X-ray diffraction, Field emission scanning electron microscope with energy dispersive spectroscopy mapping, high-resolution transmission electron microscopy, ultraviolet visible diffuse reflectance spectra, Mott Schottky curve, cyclic voltammetry curve and electrochemical impedance spectroscopy. In addition, the photocatalytic conversion mechanism was proved further by X-ray photoelectron spectroscopy. The adsorption and photocatalytic desulfurization performance of as-prepared catalysts was evaluated using ethyl mercaptan in methane gas as probe molecule. The results show that the adsorption capacity of the Ag-Mn/NS-HNbMoO6 is 222.7 μmol·g-1 in 210 min duo to the hydrogen bonding and Ag-S interaction. Ethyl mercaptan could be deeply photocatalytic oxidized to sulfates on the Ag-Mn/NS-HNbMoO6 because of the strongest photocatalytic performance. This article is protected by copyright.
