Li-ion battery materials: present and future

Metal oxide nanowires, with special physical properties, are ideal building blocks for a wide range of nanoscale electronics, optoelectronics, and chemical sensing devices. This article will describe the state-of-the-art research activities in metal oxide nanowire applications. This paper consists of three main sections categorized by metal oxide nanowire synthesis, electronic and optoelectronic devices applications, and chemical sensing applications. Finally, we will conclude this review with some perspectives and outlook on the future developments in the metal oxide nanowire research area.

Devices and chemical sensing applications of metal oxide nanowires

Urchin-like NiCo2O4 nanostructures were synthesized on a large scale via a simple hydrothermal method free of any template and catalyst. As-synthesized NiCo2O4 urchins have uniform diameters of 5 μm with numerous small nanorods radially grown from the center. Typical nanorods have diameters of 100–200 nm and lengths of about 2 μm. Studies found that urea plays an important role to determine the morphology of the products and a “rods-to-straw-bundles-to-urchins” mechanism was proposed. With a porous structure and a large surface area of 99.3 m2 g−1, the prepared NiCo2O4 urchins exhibited superior specific capacitance of 1650 and 1348 F g−1 at current densities of 1 and 15 A g−1, respectively. The capacitance loss after 2000 cycles is only 9.2% at the current density of 8 A g−1, indicating their excellent cycling stability. Photoelectrochemical cells were also fabricated on the urchin-like NiCo2O4 nanostructures with the features of fast photocurrent response and excellent stability. A high photocurrent response of about 70 μA cm−2 was observed.

Morphology evolution of urchin-like NiCo2O4 nanostructures and their applications as psuedocapacitors and photoelectrochemical cells

In this paper, we report the large-scale synthesis of ZnO nanoplatelets as thin as 10 nm. The nanoplatelets show higher efficiency in photodegrading organic dyes than ZnO nanorods do, and for the nanoplatelets, the thinner they are, the higher the performance. The photocatalytic decomposition of organic dyes (eosin B) by ZnO nanoplatelets compares favorably to the performances of ZnS porous nanoparticles and commercial Degussa P25 titania particles. This finding may have significant implications in the environment remediation and the fabrication of functional nanodevices.

Biological materials have robust hierarchical structures capable of specialized functions and the incorporation of natural biologically active components, which have been finely tuned through millions of years of evolution. These highly efficient architectural designs afford remarkable transport and mechanical properties, which render them attractive candidates for flexible electronic sensing technologies. This review provides a comprehensive overview of the fundamental aspects and applications of biological materials for flexible electronic devices and discusses various classes of biological materials by describing their unique structures and functions. We discuss the effect of the biological activity of biological materials on the improved properties in detail, because this effect overcomes the limited bioavailability and restricted morphology of materials generally encountered in traditional flexible electronic devices. We also summarize various approaches for the design and functionalization of natural materials and their applications in flexible electronic devices for use in biomedical, electron, energy, environmental and optical fields. Finally, we provide new insights and perspectives to further describe trends for future generations of biological materials, which are likely to be critical components (building blocks or elements) in future flexible electronics.

New insights and perspectives into biological materials for flexible electronics

Materials engineering plays a key role in the field of electrochemical energy storage, and considerable efforts have been made in recent years to fulfil the future requirements of electrochemical energy storage using novel functional electrode materials. Among the transition metal oxides, ternary metal oxides possess multiple oxidation states that enable multiple redox reactions. They have been reported to exhibit a higher supercapacitive performance than single component metal oxides, and seem to be a group of the most promising and low cost materials for pseudo-capacitors. This paper presents a state-of-the-art review on the research progress of developing ternary oxide nanostructures for supercapacitors, with the focus on the synthesis of one-dimensional (1-D), two-dimensional (2-D) and three-dimensional (3-D) nanostructures and their potential applications in energy storage devices. The remaining challenges toward the rational design of ternary oxide nanostructured electrodes for next-generation supercapacitors are also proposed.
