“…This compound is environmentally friendly, has mixed valence [Co II and Co III ], a spinel structure [31] and has a high theoretical capacitance (3560 F/g) [32]. Co 3 O 4 has been widely studied for its application as lithium ion battery electrodes, in pseudo-capacitances, catalysts for CO at low temperature, dye removal, ceramic pigments, fieldemission materials and magnetic material [31][32][33][34][35][36][37]. Co 3 O 4 in the form of microspheres [34,36], nanoplates and nanobelts [38] have been prepared by hydrothermal processes.…”

“…Recently, transition metal oxide nanostructures such as CuO [1,2], Co 3 O 4 [3,4], NiO [5], ZnO [6] and Cr 2 O 3 [7] have been actively studied by many groups due to various properties and applications [1][2][3][4][5][6][7]. Among the transition metals, manganese exhibits several oxidation state and forms different oxides such as MnO [8,9], Mn 2 O 3 [10,11], Mn 3 O 4 [8][9][10][11], and MnO 2 [8].…”

“…Pode-se evidenciar pelo perfil das curvas de magnetização a presença de histereses, que caracterizam materiais com propriedades ferromagnéticas. Há relatos na literatura [195][196][197][198] cobalto metálico "bulk" encontrado na literatura [199]. De modo a identificar os parâmetros que foram mais significantes para a formação do cobalto metálico, escolheu-se a temperatura de 800 °C, uma vez que os resultados de DRX e espectroscopia vibracional mostraram que na amostra FTR_CP_800 o material orgânico intercalado está decomposto e há carbono inorgânico.…”
