Catalytic conversion of ethanol over Co3O4/MgO system treated with γ-irradiation

Electrochemical preparation and properties of nanostructured Co3O4 as supercapacitor material

“…Among the transition oxides, cobalt oxide (Co 3 O 4 ) has been widely used in many fields, such as pigment for glasses and ceramics, solid-state sensors, heterogeneous catalysts, and electrochromic devices [1][2][3]. It is also regarded as a newly invented implement in supercapacitors [4][5][6][7].…”

Catalytic dehydration of bioethanol to ethylene over TiO2/γ-Al2O3 catalysts in microchannel reactors

“…Many catalysts have been studied for ethylene production via ethanol dehydration process. These catalysts are mainly pure or doped alumina [1][2][3][4]; the rest are zeolite [5], titania-silica [6], magnesium oxides [7], manganese oxides [8,9], cobalt oxides [10], chromium oxide [11], zirconium phosphite [12], silver salt of tungstophosphoric acid [13], etc. Dopants for alumina based catalysts that have been studied are mostly transition metals.…”

Catalytic dehydration of ethanol using transition metal oxide catalysts

“…Catalytic dehydration of ethanol into ethylene was investigated using different transition metal catalysts such as titanium oxides [1,2], magnesium oxides [3,4], cobalt oxides [5,6], chromium oxide [7], silver salt of tungstophosphoric acid [8], Fe 2 O 3 /Al 2 O 3 [9], FeO x /Al 2 O 3 (prepared using iron and aluminum oxides recovered from steel-pickling chemical waste and aluminum dross tailings, respectively) [10], Fe 2 O 3 , CoO, and NiO/clay [11], iron ion-exchanged mordenite [12], and Na 2 O-doped Mn 2 O 3 /Al 2 O 3 [13]. Also, ethanol dehydration was studied using aluminum and/or silicon oxide materials [14][15][16][17].…”
