SGER: Electrospinning as a Method of Fabrication of Catalytic Nanofibers

该提案的目的是电纺低聚二氧化钛/二氧化硅前体溶液以控制催化纳米棒的形成。 静电纺丝是一种从毛细管中喷射出带电射流的过程。 通过外部电场，射流被拉长并加速。 PI先前已经证明了电纺可溶性聚合物以产生3 nm至亚微米直径范围内的纤维的能力。 这种技术具有潜在的成本效益的机电控制催化纤维的尺寸，形状，分子取向，和性能，以及控制纤维放置的集成制造的两个和三维的催化剂组件。 200 m2/g的表面积是可行的。 PI将合成和测试几种适合于在过氧化物存在下催化部分氧化环辛烯的催化剂体系。 如果成功，该项目有可能指导一种新的制造技术，用于在纳米纤维上生产催化剂。

The objective of this proposal is to electrospin oligomeric titanium dioxide/silicon dioxide precursor solutions to control the formation of catalytic nanorods. Electrospinning is a process by which a charged jet is ejected from a capillary tube. Through an external electric field the jet is elongated and accelerated. The PI has previously demonstrated the ability to electrospin soluble polymers to produce fibers in the 3 nm to sub-micron diameter range. This technique has the potential for cost-effective electromechanical control of catalytic fiber size, shape, molecular orientation, and properties, as well as control of fiber placement for integrated manufacturing of two-and three dimensional nanofiber assemblies. Surface areas of 200 m2/g are feasible. The PIs will synthesize and test several catalyst systems suitable for the catalytic partial oxidation of cyclooctene in the presence of peroxides. If successful, this project has the potential to guide a new manufacturing technique for the production of catalysts on nanofibers.
