Abstract Layered structure transition metal chalcogenide compound’s such as Molybdenum sulfide (MoS₂) deposition in micro/meso porous architecture of MnO₂ could provide hybrid inter esting features. Multivalent MnO₂ is an attractive low cost and toxic free catalytic materi al for oxidation reaction and electrochemical applications. Non-ionic surfactant implica tion in mesoporous metal ion modified MnO₂ by deposition of metal chalcogenide is an ef fective composite for dye degradation applications. The low-cost pre-cursor makes it at tractive for large-scale production at industrial scale. Hence, in the present study deals with exploit the mechanism of metal chalcogenide and graphene oxide insertion More >

Abstract Geopolymers have been developed to various catalysts due to their advantages. However, low conductivity restricts their application in the electrocatalysis field. In this study, an α-Fe₂O₃/circulating fluidized bed fly ash based geopolymer (CFAG) composite anode was fabricated using a facile dip-coating method by loading α-Fe₂O₃ in the matrix of CFAG. The effects of α-Fe₂O₃ content on the composition, surface morphology and electrochemical performance of α-Fe₂O₃/CFAG composite anode were investigated. The X-ray diffraction (XRD) and scanning electron microscope (SEM) results demonstrated that α-Fe₂O₃ was successfully inlaid with the surface of amorphous CFAG matrix. The electrochemical measurements indicated that α-Fe₂O₃/CFAG More > Graphic Abstract

Abstract In this study, a magnetic P zeolite was directly synthesized by utilization of industrial solid wastes of zinc slag (ZS) and circulating fluidized bed fly ash (CFBFA) via one-step hydrothermal method. The effects of different CFBFA/ZS ratios and hydrothermal times on the as-synthesized zeolite were investigated. The X-ray diffraction (XRD) and vibrating sample magnetometer (VSM) results indicated that the magnetic P zeolite possessed well-defined crystals and superparamagnetism. The as-prepared zeolite was employed as a Fenton-like solid catalyst for degradation of direct green B dye wastewater. It was discovered that the magnetic P zeolite took the More >
