Microstructure in selective layer has played a decisive role in permselectivity of nanofiltration(NF) membranes,and nanomaterials were well-known additives that
Five Br?nsted acidic ionic liquids(ILs) were prepared and characterized by FT-IR,~1H NMR and ~(13)C NMR. Their catalytic activities for the synthesis of 2-propa
Pd/oxide/cordierite monolithic catalysts(oxide = Al_2O_3, SiO_2 and SiO_2Al_2O_3) were prepared by the impregnation method. The results of ICP, XRD, SEM–EDX, X
