Solvothermal synthesis and gas-sensing performance of Co3O4 hollow nanospheres

TWO-DIMENSIONAL NANOSHEETS-ASSEMBLED FLOWER-LIKE Co3O4 MICROSPHERES AND THEIR GAS SENSING PERFORMANCES

“…These values are higher than those of other Co 3 O 4 nanostructures. 26,27 These results con¯rm that Co 3 O 4°o wer-like microspheres possess good ethanol gas sensing property. High ethanol gas sensitivity of Co 3 O 4°o wer-like microspheres can be attributed to their open°ower-like nanostructures, which contributes to achieve di®usion of more gas molecules onto the surfaces of building blocks.…”

Effect of anions on the morphology of Co3O4 nanostructures grown by hydrothermal method and their pH sensing application

“…Co3O4 nanocrystals have also been synthesized via a facile combustion method by Feng et al [29]. Beside these several other methods have also been used for the synthesis of spinel Co3O4 nanocrystals such as sol-gel method, polyol process, solvothermal synthesis, polymer assisted synthesis, thermal decompositions, reflux/microwave assisted methods and hydrothermal synthesis for Co3O4 nanorods [30,23,[31][32][33][34][35][36]. All these methods produce high quality nanostructure with different morphologies, but the requirement of high temperature limits the compatibility of growth e.g.…”

Magnetic Cobalt and Cobalt Oxide Nanoparticles in Hyperbranched Polyester Polyol Matrix

“…Among numerous magnetic nanomaterials, cobalt (Co) and its oxides based nanoparticles have attracted particular attention because of their excellent optical [14,15], magnetic [12,13,16], and catalytic properties [17,18]. For the synthesis of such compounds, the most common methods are solvent-thermal [19][20][21], thermolysis of the carbonyl [22] or other cobalt complexes [23], and chemical reduction of cobalt salts [24,25].…”
