摘要：
Bromine mediation has been regarded as one of the most efficient ways to activate and convert methane to useful organics. This article reports the effects of active components(Rh, Ru, Pd and Pt) and supports(SiO, Mg O and AlO) on the catalysis of methane oxybromination. Among the prepared catalysts, Rh/SiOis the best in performance(CHconversion of ca. 20% and CHBr selectivity exceeding 70%). The results reveal that support type has a notable influence on the catalytic performance of Rh, especially on product distribution. The high selectivity to CHBr over Rh/SiOis attributed to its low propensity for CHBr oxidation. It was found that Rh small in particle size shows high catalytic activity and CHBr selectivity. Although silicalite-1 zeolite suffers from a certain degree of structural damage due to the presence of high temperature steam, the use of silicalite-1 as support results in a performance comparable to that of Rh/SiO.
