The Sr or Bi modified ZrO2 catalysts were prepared by the co-precipitation method. The synthesized catalysts were characterized by X-ray diffraction, temperature programmed desorption, and N2 adsorption/desorption methods. All the synthesized catalysts were tested in the conversion of ethanol to light olefins. The results show that Sr or Bi modified ZrO2 catalysts have a remarkable effect on the surface...
