La2O3/CaO catalyst derived from eggshells: Effects of preparation method and La content on textural properties and catalytic activity for transesterification
This research aims to develop the La2O3/CaO catalyst derived from eggshells by physical mixing and impregnation methods at various La contents. The synthesized catalyst was characterized using several techniques. The catalyst activity was tested via transesterification. It was found that La2O3/CaO o...
