Preparation and Influence Factors of SO42-/ZrO2 Nanotube Catalyst
ZrO2 nanotube carrier was obtained using a direct anodization method. Then SO42-/ZrO2 nanotube catalyst was developed in the sulfuric acid solution through ultrasonic dipping processing. The morphology, thermal stability and crystal forms of catalysts were analyzed, and the influence factors of catalytic activity were studied. The results presented in this work show that the catalyst activity was highest under the following conditions: the mass fraction of sulfuric acid solution was 50 %, the ultrasonic dipping time was 20 min, the suitable calcination temperature was 400 °C and the calcination time was 60 min.
