Synthesis of ZnO-CoO/Al2O3 nanoparticles and its application as a catalyst in ethanol conversion to acetone

In this work, ZnO-CoO/Al2O3 nanoparticles were synthesized and used as a catalyst for the dehydrogenation of ethanol to produce acetone. The catalyst was characterized by transmission electron microscopy (TEM) and Brunauer–Emmett–Teller (BET) to identify the particle size and surface area, which wer...
