资源简介：

This proposal aims to investigate the effects of nitridation on the structural transformation of mixed metal oxides, and to determine how structural and electronics changes relate to catalytic activity during ammonia decomposition. We will compare the structural modifications and catalytic properties of supported and non-supported catalysts based on the transition metals Mo, Co, Fe, and Ni, employing hydrotalcite-derived supports with Mg and Al (HT). In-situ XAS-XRD studies, in combination with mass spectrometry, will allow us to gain insights into how the catalyst composition and structure influence the catalytic activity and stability during ammonia decomposition at relevant conditions, including the metal nitride formation when exposing the catalyst to ammonia at elevated temperatures.
