Adsorption and conversion of ethyl mercaptan on the surface of Ag‐Mn/NS‐HNbMoO₆

Abstract

BACKGROUND The composite photocatalyst Ag‐Mn/NS‐HNbMoO6 was prepared by exfoliation‐recombination method, and applied for adsorption and conversion of ethyl mercaptan. RESULTS The results showed that the interfacial charges could be transferred during the composite process because of the difference of the Sanderson electronegativity of Ag, Mn and H. The adsorbing capacity of the Ag‐Mn/NS‐HNbMoO6 is 222.7 μmol·g−1 which is more than 4 times as much as the adsorbing capacity of HNbMoO6 nanosheet duo to the hydrogen bond interaction and Ag–S interaction. Ethyl mercaptan could be photocatalytic converted in the deepest to sulfates on the Ag‐Mn/NS‐HNbMoO6 because of the strongest photocatalytic performance. CONCLUSIONS Ag‐Mn/NS‐HNbMoO6 composite is a high‐performance photocatalytic conversion desulfurization catalyst with a strong adsorptive‐oxidative‐photocatalytic performance. © 2022 Society of Chemical Industry (SCI).
