Single-Crystalline-Phase Mo3VOx: An Efficient Catalyst for the Partial Oxidation of Acrolein to Acrylic Acid



original image

Being single (crystalline): Four single-crystalline-phase Mo3VOx materials are utilized as catalysts for the partial oxidation of acrolein to acrylic acid. The crystalline structure has a clear effect on catalytic performance. Mo3VOx with a trigonal crystalline structure is the most efficient catalyst: 99.8 % conversion with 93.9 % selectivity for acrylic acid is obtained at a temperature (217.3 °C) much lower than that previously reported.
