American Chemical Society WebJul 1, 2024 · The catalyst was prepared at 550 °C in a He flow for 1 h, followed by the adsorption of NH 3 at 100 °C for 1 h. After saturation, the catalyst was purged by a He flow for 3 h to remove the physically adsorbed ammonia on the sample. Subsequently, desorption of NH 3 was carried out from 100 to 600 °C with a heating rate of 2.5 °C/min.
