【求助】 请问广州有什么地方可以测以下的催化反应
|

最近做了一个无机材料，想测测其催化性能，但是不是搞这一块的，所以想请教请教大家，尤其是广州地区的，哪里有可以测这样条件的设备呢？ 文献具体如下“As a kind of important inorganic functional material, lanthanide orthovanadates are also widely used as catalysts for the oxidative dehydrogenation of propane (ODP) to propene. But in the case of m-LaVO4, it is an unstable active phase that cannot stabilize the surface active sites, which are oxygen vacancies associated with V4+ ions. Therefore m-LaVO4 is not regarded as a good candidate.9 The catalytic performances of both m-(as indicated in Figure 1a, noted as sample a) and t-LaVO4 (as indicated in Figure 5a,c, noted as samples b and c, respectively at 500 °C within 240 min are shown in Figure 10. For samples a and b, whose BET surface areas are almost the same (56.0 and 59.9 m2/g, respectively), the C3H8 conversion of sample b is much higher than that of sample a. Even for sample c, whose BET surface area (7.1 m2/g) is much smaller, a relatively higher C3H8 conversion could be achieved. The selectivity of the reaction is somewhat lowered for both b and c, but the great increase of C3H8 conversion can compensate this loss, leading to an enhanced yield of C3H6.” [ Last edited by wellok101 on 2009-2-28 at 22:33 ] |
