Three Way Catalyst

This work aimed at exploring a new kind of purification catalysts for fuel ethanol engine exhaust. Platinum loaded on Ce0.5Zr0.5O2 was prepared by impregnation method and characterized by X-ray diffraction, Brunner–Emmet–Teller measurements (BET), temperature-programmed reduction of hydrogen, scanning electron microscope, and X-ray photoelectron spectra. The three-way catalyst platinum/ceria–zirconia/fw is prepared with the paste ball mill coating technique. And the catalytic performance is evaluated under simulated fuel ethanol engine exhaust gas condition. The catalysts not only show excellent low-temperature performances and several-way catalytic activities for carbon monoxide, hydrocarbons, nitrogen oxides, and acetaldehyde but also have better high-temperature resistance. The addition of sulfur dioxide to feedstream degrades the performances of the catalysts.
