Abstract:
A porous hexangular ring-core NiCo2O4 nanosheet/NiO nanoparticle composite has been synthesized using a hydrothermal method followed by an annealing process in air. The as-obtained composite as an anode material exhibits a high initial discharge capacity of 1920.6 mA h g(-1) at a current density of 100 mA g(-1) and the capacity is retained at 1567.3 mA h g(-1) after 50 cycles. When it is utilized as a catalyst for CO oxidation, complete CO conversion is achieved at 115 °C and a catalytic life test demonstrates the good stability of the composite.

Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
