Use one of the previously found papers, or find another one which uses metal catalysts supported on a support, and read the experimental section part regarding catalyst preparation. (Some papers may use commercial catalysts, do not use this paper then, find another one where authors prepare catalysts themselves.) Answer the following questions: a) What support is used for the catalyst preparation? Is it suitable for this reaction keeping in mind the reaction components and reaction temperature? Explain why. (10%) b) How is the catalyst synthesized and dried/calcined/reduced as applicable? Explain in detail each step and try to explain the choice of conditions. Provide your suggestions what you think could be done better or differently, and if everything makes sense. (25%) c) Imagine if you were to synthesize a similar catalyst yourself via wet impregnation/ion-exchange using an aqueous solution (pH 6) of the metal precursor and their support. Would you use a cation or an anion containing your metal to ion-xchange on the surface? Explain. (10%)
