本项目拟结合静电纺丝与热处理技术，选择合适的电纺前体、含氮聚合物和金属前体，同时优化电纺过程各项参数，建立和完善一种简单、可控制备自支撑非贵金属/金属氧化物纳米粒子负载氮掺杂碳纳米纤维复合材料的方法，实现非贵金属/金属氧化物纳米粒子负载及氮掺杂的双功能化；研究氮原子和纳米粒子引入形式和存在方式对复合材料结构、性质的影响，提高电催化活性及稳定性；用于燃料分子的电催化研究，同时构建相应的电化学生物传感器，实现对生物分子的灵敏、选择性检测。

The project is focus on developing a simple and controllable method to synthesize a free-standing non-noble metal/metal oxides nanoparticles loaded nitrogen-doped carbon nanofibers (M/MO-NCNFs) composites via electrospinning and thermal treatment technique. By selecting appropriate precursors of carbon, nitrogen and metal nanoparticles, and optimizing parameters of electrospinning process to realize the bifunction of CNFs. Effect of introduction strategies and existence form of nitrogen and M/MO nanoparticles on the structure and character of composites will be studied. Finally, we will investigate the electrocatalytic properties of the prepared composites in fuel cell and construct electrochemical biosensors with high sensitivity and good selectivity for biological molecules analysis.
