Using solid complex molecular precursor [bis(salicylaldehyde)ethylenediiminecobalt(II)], [Co(salen)], a simple and surfactant-free method to synthesize Co 3 O 4 nanoparticles was proposed. Cubic-phase Co 3 O 4 nanoparticles of size 30–50-nm could be produced by thermal treatment of the Co(salen) in the air at 500°C for 5h. The as-prepared samples were characterized...
Powdered Prussian blue analogues (PBAs) and PBAs confined in ordered mesoporous silica monoliths were used as oxide precursors through thermal treatment under an oxidizing atmosphere. The study focuses on the transformation of the alkali cation-free CoCo PBA of chemical formula K 0.1 Co II4 [Co III (CN) 6 ] 2.7 ·20H 2 O. The compounds were characterized...
