a new nano-sized cobalt(ii) coordination polymer, (col1).0.5dmf.1.5ch3oh(1); [h2l1 = 5-(4-carboxy phenyl azo) salicyilic acid] has been synthesized by a sonochemical method. the thermal stability of compound 1 was studied by thermo- gravimetric and differential thermal analyses. nano-structure of this coordination polymer was characterized by elemental analyses, ir spectroscopy,  powder x-ray d...

Highly efficient and chemically compatible LnxSr1-xCoO3-delta (Ln = La, Sm, Gd, ...)/Co3O4 electrocatalysts for oxygen reduction reaction are presented and the very low cathode polarization resistances and excellent performances implied their promising application for developing intermediate-temperature solid oxide fuel cells (SOFCs), as well as potential application for oxygen separation membr...

A generalized hydrothermal strategy for fabricating three-dimensional (3D) battery electrodes is presented. The hydrothermal growth deposits electrochemically active nanomaterials uniformly throughout the complex 3D mesostructure of the scaffold. Ni inverse opals coated with SnO2 nanoparticles or Co3O4 nanoplatelets, and SiO2 inverse opals coated with Fe3O4 are fabricated, all of which show att...

Cubic ordered mesoporous Co3O4, prepared via the nanocasting pathway using KIT-6 as hard template, was found to be an excellent catalyst for low temperature CO oxidation, with the activity clearly depending on surface area and pore systems of the catalysts.

A facile in situ vapour phase hydrothermal (VPH) surface doping approach has been developed for fabrication of high performance S-doped Co3O4 electrocatalysts with an unprecedentedly high surface S content (>47%). The demonstrated VPH doping approach could be useful for enrichment of surface active sites for other metal oxide electrocatalysts.

Herein, we introduce a specially designed domain-confined macroporous catalyst, namely, the Co3O4 nanocrystals anchored on a TiO2 nanotube array catalyst, which was synthesized by using the mercaptoacetic acid induced surface-grafting method. This catalyst exhibits much better performance for catalytic soot combustion than the conventional TiO2 powder supported one in gravitational contact mode...

Composites of transition metal oxides (TMOs)/polymers have many modern technological, industrial, and biological applications. Co3O4 CuO nanoparticles (Nps) were synthesized by sol–gel. Then they are doped into poly(methyl methacrylate) (PMMA) via the solution casting method. The obtained Nps nanocomposites then investigated using several techniques. XRD HR-TEM indicated high purity face-center...
