Potassium impregnated mixed oxides of lanthanum and magnesium in 1:1 to 1:5 atomic ratios were prepared by co-precipitation at a constant pH. These were characterized by FEG–SEM–EDX, TEM, Powder XRD, Hammett indicators and acid/base titration and, were evaluated as heterogeneous catalysts...

A series of Li/CaO catalysts has been prepared by impregnating 0.5–5.0 wt% Li in CaO by wet chemical method. Prepared Li/CaO catalysts have been characterized by powder X-ray diffraction, scanning electron and transmission electron microscopy and Brunauer–Emmett–Teller (BET) surface area...

The use of MgO impregnated with KOH as heterogeneous catalysts for the transesterification of mutton fat with methanol has been evaluated. The mutton fat (fat) with methanol (1:22 M ratio) at 65 °C showed  98% conversion to biodiesel with 4 wt% of MgO–KOH-2011MgO–KOH-X (X = wt% of...

Lithium impregnated calcium oxide has been prepared by wet impregnation method in nano particle form as supported by powder X-ray diffraction and transmission electron microscopy. Basic strength of the same was measured by Hammett indicators. Calcium oxide impregnated with 1.75 wt% of lithium...
