The montmorillonite-chitosan composite could provide hydrophobicity and functional groups to enhance the performances of montmorillonite in wastewater treatment. The composites showed good abilities to remove the pollutants, such as heavy metals and dyes. However, the comparative adsorption of multiple metals on the fixed C-content nanocomposite needs to be studied further. This paper presents the...
Selective oxidation of CO in H 2 -rich streams is performed over a series of CuO–MnO x –CeO 2 catalysts prepared by hydrothermal (CuMC-HY), co-precipitation (CuMC-CP), impregnation (CuMC-IM) and citrate sol–gel (CuMC-SG) methods. The catalysts are characterized by N 2 adsorption/desorption, XRD, SEM, HR-TEM, TPR and XPS techniques. The results show that the catalyst...
