Synthesis and mechanism of MoS2 and graphene oxide insertion in porous multi metal ion modified MnO2 nanorods for dye degradation

Abstract

Layered structure transition metal chalcogenide compound’s such as Molybdenum sulfide (MoS2) deposition in micro/meso porous architecture of MnO2 could provide hybrid interesting features. Multivalent MnO2 is an attractive low cost and toxic free catalytic material for oxidation reaction and electrochemical applications. Non-ionic surfactant implication in mesoporous metal ion modified MnO2 by deposition of metal chalcogenide is an effective composite for dye degradation applications. The low-cost pre-cursor makes it attractive for large-scale production at industrial scale. Hence, in the present study deals with exploit the mechanism of metal chalcogenide and graphene oxide insertion in porous manganese oxide matrix. The as prepared l surface properties of the Nickel and cobalt doped manganese oxide/MoS2 composite catalyst have shown effective congo red dye degradation activity. The complete color disappearance appeared after interaction with the composite catalyst.
