As an essential feedstock for the petrochemical industry and dominant energy source; crude oil exploitation and further refining draw much attention in recent years.  However, because of the global economical expansion the world crude oil reserves can only meet energy the demand for at most 50 years at current consumption rate. But is should be less than that due to the increasing rate of GDP in the developing countries.  As a result, effective conversion of crude oil into target petrochemical and fuel feedstock becomes the target in petrochemical industry. Ethylene is the basic raw material in the petro-chemical industry and the production over the last 25 years being spectacular; over 75 million metric tons of ethylene are produced and used in 2009, worldwide. The abundant accessibility of the light hydrocarbon, e.g. ethane is mainly derived from natural gas or naphtha cracking. Naphtha or ethane cracking in presence of steam remains the dominant source of ethylene globally[1], but the high endothermicity of this process consumes lot of energy and produces heavy amount of coke. Thus form industrial viewpoint low temperature dehydrogenation of ethane to ethylene have the potential to replace the steam cracker.Ultrathin TiO2 Nanowires were prepared by the hydrothermal method in presence of surfactant, and Mo was impregnated by wet impregnation method. The catalyst was found to be highly active for the selective dehydrogenation of ethane to ethylene. The catalyst was characterized by XRD, N2-sorption, ICP-AES, TPR, XPS, Raman, SEM, TEM and EXAFS. The influence of various reaction parameters like temperature, Mo-loading, time-on-stream, GHSV (ml g-1 h-1) and the reusability of the catalyst were studied in detail. An ethane conversion of 83 % with 94 % selectivity of ethylene was achieved after 3 h of reaction.[1] Choudhary. V. R.; Mulla, S. A. R, AIChE journal, 1997 , 43, 1545-1550.
