由具有氧敏特性的TiO2与Nb2O5形成的不含贵金属催化剂的复合材料,其氧分压特性、空燃比特性及温度特性的比单纯材料有明显改善.
The composites formed non noble metal catalyst with TiO2 and Nb2OS5 of oxygen sensing properties are more improved than the oxygen partial pressure properties, air excess ratio properties and temperature properties of the two intrinsic materals respectiv
