Hollow mixed metal oxides have received much attention owing to their great performance for wide potential applications. Here, we have successfully prepared hollow Co− Mo mixed oxide nanostructures with controlled structure and compositions, including hollow Co 3 O 4 /CoMoO 4 heterostructures and ball-in-ball CoMoO 4 nanospheres. Uniform CoMohybrid precursors are prepared through one-pot solvothermal method and then transformed into hollow structures after thermal treatment. Importantly, this strategy can be used to prepare other ternary Mo-based oxides. In view of the unique heterostructure with hollow structure, the Co 3 O 4 /CoMoO 4 heterostructures exhibit much better electrocatalytic activity for the oxygen evolution reaction than CoMoO 4 . Moreover, the as-synthesized carbon-coated Co 3 O 4 /CoMoO 4 nanospheres show excellent lithium storage properties. Our result described here provides a method to fabricate other mixed metal oxides with complicated structure.

“…25 Binary metal oxides were often synthesized by hydrothermal, 18 template, 26 and solvothermal methods. 27 In these methods, some surfactants, templates, and complicated instruments might be needed, which limit the application of metal oxides as green catalysts. The dealloying method is a flexible and simple method for preparing metal oxides without surfactants.…”

The nonpollution electrochemical synthesis of NH3 under ambient conditions is a hopeful candidate to the industrial Haber–Bosch process in harsh conditions. Potential catalyst exploration is very important to improve NH3 production and Faraday efficiency. Herein, we synthesized amorphous CoMoO4 catalysts with nanoporous structures by chemical dealloying for the N2 reduction reaction (NRR). At −0.50 V versus reversible hydrogen electrode, the CoMoO4 catalyst exhibits a high NH3 yield of 30.2 μg h–1 mgcat –1 and a Faraday efficiency of 3.8% in 0.1 M phosphate buffer saline. The enhanced NRR property is ascribed to modified structures by a binary metal synergistic effect and more active site exposure because of the amorphous structure. Compared with MoO2, mixed oxide (MoO2 and Co3O4), and crystal CoMoO4, binary metallic oxide of amorphous CoMoO4 is more favorable in N2 activation and protonation.

“…Moreover, the development of high-performance LIBs with enhanced capacity, lifespan and rate performance are imperative. As everyone knows, the performances of LIBs have a great relationship with the species of electrode materials [4,5]. In a variety of anode materials, transition metal oxides (TMOs) have been widely studied due to their high theoretical capacity, low cost and environmental friendly in recent years [6][7][8].…”

Three-dimensional nickel cobalt sulphide (NiCo 2 S 4) nanotubes-graphene aerogel composites (NGAs) are firstly assembled by an electrostatic interaction between the diallyldimethylammonium chloride-modified NiCo 2 S 4 nanotubes and graphene oxide (GO) sheets, followed by a steerable hydrothermal and freeze-drying process. The final samples are characterised by scanning electron microscope, transmission electron microscopy, X-ray diffraction and Brunauer-Emmett-Teller. The results reveal that the NiCo 2 S 4 nanotubes with a uniform diameter of about 200 nm tightly anchor onto the crumpled surface of graphene sheets and GO sheets self-assemble into an interconnected porous structure. When the composites are evaluated as an anode for lithium-ion batteries (LIBs), presenting an extremely admirable cycling stability (967.5 mAh g −1 after 100 cycles at a current density of 100 mA g −1) and excellent rate capability (as high as 654.7 mAh g −1 at a large rate of at 2000 mA g −1). This work proved that the NGAs may have a great application in LIBs.
