催化剂表面修饰对催化元件性能的影响

Effect of Catalyst Surface Modifying on Methane Sensor Properties

研究了催化剂载体孔径、比表面积与催化元件工作性能关系，催化剂表面的酸性和碱性修饰以及稀土助剂的加入对催化元件工作性能的影响．

The relationship of aperture and specific surface area of catalyst supporter and the performance of the catalystmodified sensor, and the influence of acidic and basic modification of catalyst surface as well as the addition of rare earth on performance of the sensor are studied. The conclusion that to have the calcined supporter surface been processed with acid or alkali is helpful in improving the performance of the sensor is obtained.
