Controlled synthesis of highly active mesoporous Co3O4 polycrystals for low temperature CO oxidation

The effect of crystallinity on photocatalytic performance of Co3O4 water-splitting cocatalysts

“…The other two peaks at 803.1 and 787.1 eV can be attributed to its shake up satellite peaks. 25 To investigate the photocurrent generation capabilities of WO3 and Co3O4/WO3, linear sweep voltammetry was utilized under dark and light condition using Ag/AgCl as the reference electrode. Figure 6 shows the PEC current-voltage curve of bare WO3 and Co3O4/WO3 film.…”

Effect of microwave power on the thermal genesis of Co3O4 nanoparticles from cobalt oxalate micro-rods

“…5), which is accompanied by an endothermic effect at 918 ºC (Fig. 6) [3,12,22,[24][25][26]29,34,35]. The first band is assigned to Co 3+ ions in an octahedral positions whereas the second one is due to the Co 2+ ions in tetrahedral positions.…”

“…Cobalt oxide based catalysts has been thought to be the active species in a variety of chemical reactions. The recent work of Feng et al [12] demonstrated that Co 3 O 4 is capable to convert CO completely to CO 2 at temperature as low as −70 ºC. Co 3 O 4 showed high activity towards the gas-phase oxidation of 1,2-dichloroethane at 350 ºC with a 100% selectivity towards CO 2 [13].…”

Cobalt-aluminum mixed oxides prepared from layered double hydroxides for the total oxidation of benzene

“…Generally, Co 3 O 4 was prepared by thermal decomposition of cobalt precursors such as Co(NO 3 ) 2 [14], Co(OH) 2 [13], Co(CO 3 ) 0.5 (OH)0.11H 2 O [12,13], CoC 2 O 4 [15], and CoO(OH) [16], and Co 3 O 4 with different morphologies or structures such as nanoparticles, nanorods, nanocubes, nanotubes, and mesoporous structures has been reported to show different activities. On the other hand, layered double hydroxides (LDHs) have attracted much attention as an effective precursor of mixed metal oxides due to their versatility and unique structural properties.…”
