Abstract

This paper reports on the synthesis and characterization of a heterodinuclear complex precursor for LaNiO3 perovskite obtaining, prepared in La(CH3COO)3 – Ni(CH3COO)2 – AOH – DMF system (AOH = 2- [(diethylamino) methyl]-6- ethylphenol and DMF = dimethylformamide). According to the XRD pattern, LaNiO3 obtained by calcination (700 0C, 10 minutes) of complex precursor is single phase with hexagonal perovskite-like structure. The relatively high values of specific surface area of LaNiO3 samples obtained, sustain their posible catalytic activity..
