Gas-Sensing Catalysis Characteristics of CeO_2-TiO_2 Co-Oxide

Fu Jun 1,He Ping 2 and Dong Mingyou 3(1 Department of Physics,Hainan Normal University,Haikou 571158,China) (2 Department of Physics,Guangxi Teachers College,NanNing 530001,China) (3 Haikou Keyu Electronic Component Factory,HaiKou 571100,China)  
CeO 2 TiO 2 co oxide,instead of platinum (Pt) catalyst,is prepared by sol gel methods to make gas sensing catalyst elements under different processing conditions.That catalysis density and the process to make affect gas sensing catalysis characterics in C 4H 10 gas are studied.The result shows that catalysis of CeO 2 TiO 2 co oxide possesses high gas sensitivity.The gas sensitivity refers to the density of catalyst,the sintering temperature of catalyst,carrier and surface characteristics improvement.The gas sensitivity of CeO 2 TiO 2 co oxide is as good as that of platinum catalysts by choosing the best making technology,and it has the anti toxic property gas.
