The role of m-ZrO2 in the selective oxidation of ethanol to acetic acid employing PdO/m-ZrO2

Synthesis, characterization, and photocatalytic efficiency of a new smart PdO oxide nanomaterials for using in the recycling and sustainable wastewater treatment

“…Recently, palladium metal (Pd) and its oxide (PdO) have received special attention and extensive investigation due to their unique properties as catalysts because they possess high catalytic potency at low temperatures and low volatility at high temperatures. They have wide applications [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] in methane combustion [25][26][27][28], carbon monoxide oxidation [29][30][31][32], catalyzing several organic conversions and reactions, like reduction reactions, hydrogenations of unsaturated olefins, and carbon-carbon cross-coupling formation [33][34][35], ethanol oxidation; it decomposes ethanol through decarbonylation and dehydrogenation, releasing CO and H species and environmental redemption applications when incorporating Pd or PdO with TiO 2 . This incorporation reduced the band gap of TiO 2 .…”

Sorption and Reaction of Biomass Derived HC Blends and Their Constituents on a Commercial Pt–Pd/Al2O3 Oxidation Catalyst

“…8 Weighted CO 2 yield, the blue line shows the expected CO 2 yield with the same conversion of HC in the blend as in the pure substance tests, black is the actual amount of CO 2 released from the blend. On the left side the HC is shown in the composition of blend 1 and on the right side of blend 2, filtered by a Savitzky-Golay-Function of 3rd polynomial order and a window size of 90, T = 383 K and GHSV = 60,000 h −1 , gas composition: 8% H 2 O, 8% O 2 , 0% CO 2 , HC: see legend, balance: N 2 also lead to the formation of acetaldehyde and acetic acid [38][39][40]. It is known that Al 2 O 3 has a poor adsorption behavior for ethanol because of its low specific surface area [41].…”

Particle size effect of ZrO2 supports on catalytic liquid-phase oxidation of phenol over Pt/CeO2-ZrO2-Bi2O3/ZrO2 catalysts

“…Some ZrO 2 -supported catalysts show higher activities compared to other supported catalysts for the oxidation of carbon monoxide, methane, etc [10][11][12][13][14][15]. In addition to gas-phase oxidation, ZrO 2 has also been applied to liquid-phase oxidation, and ZrO 2 -supported catalysts have demonstrated promising results in processes such as selective oxidation [16][17][18] and wastewater pollutant treatment, e.g. Kraft plant wastewater [19], carboxylic acid [20,21], N, N-dimethylformamide [22].…”
