American Chemical Society Webbase and possibly as Lewis acid catalyst (Dahm & Uhlenbeck, 1991; Dahm et al., 1993). As a base, the metal hydroxide bound specifically to the hammer-head RNA initiates the reaction by abstracting the hydrogen atom from the 2'-hydroxyl at the cleavage site; as a Lewis acid catalyst, the metal is believed

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.
