Electrospun nanofiber materials for energy and environmental applications
Abstract
<p>Electrospinning is the one of themost versatile techniques to design nanofiber materials with numerousapplications in the fields of energy conversion, catalytic chemistry,liquid and gas filtration.<sup>1</sup> By electrospinning, complexstructures can be designed from a rich variety of materials includingpolymers, metals, ceramics and composite, with the ability to controlcomposition, morphology and secondary structure and tailor performanceand functionality for specific applications. Moreover, with recentdevelopments in the design of electrospinning equipment and availabilityof industrial-scale electrospinning technologies with production ratesof several thousands of square meters per day new opportunities forelectrospinning are imminent. With this, the advanced research onmaterials performed in our labs is getting closer to thecommercialization of new products for applications in fields of energyand environment.</p><p>An overview will be given onelectrospinning activities at DTU Energy that address the sizablechallenges in energy and environmental applications by electrospinning:1. Electrospun perovskite oxide nanofiber electrode for use in solidoxide fuel cells. In this application, a (La<sub>0.6</sub>Sr<sub>0.4</sub>)<sub>0.99</sub>CoO<sub>3-δ</sub>cathode was shaped into 3-dimensional thin-film by so-gel assistedelectrospinning method combined with calcination and sintering; 2.Electrospun nanofiber materials for gas adsorption. Both the advantagesand challenges of using electrospun nanofiber materials will bediscussed, in terms of electrochemical performance, surface area,packing efficiency and mechanical stability.</p>
