Preparation method and application of hydrophilic nitrogen-doped carbon nanofiber dense network
The invention relates to a preparation method and application of a hydrophilic nitrogen-doped carbon nanofiber dense network. The preparation method comprises the following specific steps: 1) puttingporous aluminum oxide into a ceramic boat, then putting the ceramic boat into a resistance furnace, introducing inert gas, carrying out heating, then introducing mixed gas of acetylene and inert gas,and growing carbon nanofibers on the surface of the ceramic boat after a reaction; 2) stripping the carbon nanofibers obtained in the step 1) from the surface of the ceramic boat, putting the carbon nanofibers into a resistance furnace, introducing inert gas, carrying out heating, introducing mixed gas of ammonia gas and inert gas, and converting the carbon nanofibers into nitrogen-doped carbon nanofibers; and 3) dispersing the nitrogen-doped carbon nanofibers obtained in the step 2) in water, then carrying out vacuum filtration on the obtained mixed solution, and compressing the nitrogen-doped carbon nanofibers in the process of filtration to obtain the hydrophilic nitrogen-doped carbon nanofiber dense network.
本发明涉及一种亲水性氮掺杂碳纳米纤维致密网络的制备方法及应用。具体步骤为：1)将多孔氧化铝放入陶瓷舟中，然后将陶瓷舟置于电阻炉中，通入惰性气体，加热后再通入乙炔和惰性气体的混合气，反应后在陶瓷舟的表面生长碳纳米纤维；2)将步骤1)得到的碳纳米纤维从陶瓷舟表面剥离，再置于电阻炉中，通入惰性气体，加热后再通入氨气和惰性气体的混合气，碳纳米纤维就转化为氮掺杂碳纳米纤维；3)将步骤2)得到的氮掺杂碳纳米纤维分散于水中，然后将得到的混合液进行真空过滤，在过滤的过程中对氮掺杂碳纳米纤维进行压缩，得到亲水性氮掺杂碳纳米纤维致密网络。
