The Ce3W2SbOx catalyst provided high activity and broad operation window. The Ce3W2SbOx catalyst has stronger Lewis acid sites and abundant Ce3+ and active surface oxygen species. L-H mechanism is the dominate process for low temperatures. Ce3W2SbOx catalyst presents an adequate tolerance to SO2, hydrothermal aging and large GHSV value.
