Ethanol dimerization to Ethyl acetate and hydrogen on the multifaceted copper catalysts

One-Pot Ethyl Acetate Production from Ethanol Photooxidation on Rutile TiO2(110): Strong Photon Energy Dependence

“…However, these processes will cause corrosion and toxicity issues to the apparatuses and environment . Recently, one-pot EA synthesis from EtOH dehydrogenation via heterogeneous catalytic process has attracted lots of attention because of its simplicity, noncorrosion, less toxicity, and competitively low cost. ,,− However, efficient dehydrogenation of EtOH into EA requires high temperature (200–260 °C), which is still highly energy-consuming. , Compared with thermal catalytic processes, photocatalysis may provide a green and mild catalytic route for the direct dehydrogenation of EtOH into EA.…”

“…According to a series of catalytic investigations on EA formation from EtOH over copper-based catalysts, , the formation of EA from EtOH will occur via either a Tischenko-type (self-coupling of CH 3 CHO) or a hemiacetal (cross-coupling of CH 3 CHO and C 2 H 5 O) reaction mechanism. Here, CH 3 CHO Ti can be easily produced from EtOH photooxidation on R-TiO 2 (110) under UV light irradiation.…”

Insights and Activation Energy Surface of the Dehydrogenation of C2HxO Species in Ethanol Oxidation Reaction on Ir(100)

“…Our choice of (100) surface also comes from the following reasons. Firstly, although (111) is often more stable than (100), the (100) surface demonstrates the highest activity among low index surfaces [19,36] and are present in Ir nanoparticles. [72,73] Secondly, Chang, et al recently synthesized EOR catalysts with Ir(100) as dominant surfaces.…”

“…[1] In ethanol oxidation reaction (EOR) that takes place in direct ethanol fuel cells [2][3][4][5] or in hydrogen production via ethanol steam reforming, [6][7][8][9][10][11] ethanol dehydrogenation is the first step in the complex reaction network and therefore has been an active area of research. [12,13] Additionally, ethanol dehydrogenation is the first elementary reaction and plays important roles in the synthesis of acetaldehyde, [14][15][16][17][18] ethyl acetate, [19][20][21] butadiene, [22,23] butanol, [24][25][26] polyvinyl alcohol, [27] aromatic alcohols, [28] and bio-fuels. [29,30] Different degree of ethanol dehydrogenation is involved depending on the overall reaction of interest.…”
