An emphasis on the dehydroxylation processes and anionic mass-loss facilitation is discussed. Moreover, in situ specimen cooling revealed the retention of interlayer nitrates. At lower acceleration voltages, an increased dehydration rate of the LDH cationic layers is observed during irradiaton. It was found that TEM conditions profoundly affected the decomposition behaviours. In parallel, nitrogen K edge attenuation demonstrated interlayer mass-losses. During 300 kV irradiation, a pre-peak evolution in the oxygen K edge highlighted a transition to metal oxide species. In addition, a compositional change was established by electron energy loss spectroscopy (EELS). The generation of pores and crystallographic breakdown of the LDH routinely occurred. The Ni–Fe LDHs were susceptible to significant structural decompositions during electron irradiation. The initial structure possessed a flat hexagonal morphology made up of crystalline domains with a well-defined hexagonal crystal structure.
