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.

该提案的目的是静电纺丝低聚二氧化钛/二氧化硅前体溶液以控制催化纳米棒的形成。 静电纺丝是从毛细管中喷射带电射流的过程。 通过外部电场，射流被拉长并加速。 PI 此前已展示了静电纺丝可溶性聚合物生产 3 纳米至亚微米直径范围纤维的能力。 该技术具有对催化纤维尺寸、形状、分子取向和性能进行经济有效的机电控制的潜力，以及对二维和三维纳米纤维组件集成制造的纤维放置控制的潜力。 200 m2/g 的表面积是可行的。 PI 将合成并测试几种适用于在过氧化物存在下催化部分氧化环辛烯的催化剂系统。 如果成功，该项目有可能指导纳米纤维催化剂生产的新制造技术。
