Considering the risks of hydrothermal deterioration in vehicles, power plants, and oceangoing vessels, V2O5-WO3/TiO2 catalysts were subject to hydrothermal and thermal aging at 600, 625, 635, and 650 °C for 4–48 h. The different ratio and significant loss of active sites are main reasons for catalys...
