摘要
嵌入表面分子方法是描述非均相催化反应中所定义的活性中心的新方法。该法是将活性中心看作一个“表面分子”。嵌入表面分子方法强调了在非均相催化中需要考虑生成键的思想并充分利用其它化学领域尤其是均相催化方面的成键理论。利用这一方法较详细地分析了以合成气为原料、以负载型的铑为催化剂进行反应生成Ｃ２以上含氧化合物及烃类等产物机理。
The embedded surface molecule (ESM) method is a new systematical approach to describe the active site defined for a heterogeneous catalytic reaction, which considers the active site as a 'surface molecule'.The concept of ESM lays emphasis on the need to take account of bond forming reaction in heterogeneous catalysis and to take advantage of the theory of bond formation that has been developed in other branches of chemistry, particularly in homogeneous catalysis. Using the ESM method, the mechanism is fully discussed of formation of C 2 + oxygenates and hydrocarbons from synthesis gas over a supported rhodium catalyst.
