1 In the Haber process for the manufacture of ammonia, why is the heterogeneous catalyst iron in a finely divided state?A A to increase its surface area B to produce the maximum reduction in the activation energy C to reduce its loss during the reaction D to reduce its surface area 相关...
The Haber–Bosch process for ammonia synthesis has been suggested to be the most important invention of the 20th century, and called the ‘Bellwether reaction in heterogeneous catalysis’. We examine the catalyst requirements for a new low-pressure, low-temperature synthesis process. We show that ...

industrial catalyst under conditions close to those of the Haber–Bosch process to determine whether dynamic bulk nitridation occurs. This method and the experimental setup were recently employed for the direct in situ observation of the bulk structural properties of working catalysts. [16] Ammo- nia...
