Abstract:Annealing step is a critical step in the hydrothermal assisted synthesis of La/Ni oxides such as LaNiO3−δ
(LNOA) and La2NiO4+δ
(LNON). In the current study, we have discovered the interlink between the atmosphere and temperature conditions which dictate the product formed. La/Ni nitrate precursors were subjected to a hydrothermal synthesis followed by an annealing step at appropriate temperature and varying atmosphere resulting in the synthesis of the corresponding oxides.… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
