碳化钨/碳复合纤维制备及其电解水析氢性能OA
Preparation of tungsten carbide/carbon composite fiber and its hydrogen evolution performance in electrolytic water
以聚丙烯腈、N,N-二甲基甲酰胺、偏钨酸铵(AMT)为原料,采用静电纺丝法制备了碳化钨/碳(WC/C)复合纤维,对其微观形貌以及析氢活性进行了表征.结果表明,纺丝液中不同偏钨酸铵含量情况下都可以获得连续的纺出纤维,但热处理后的WC/C复合纤维长度随着偏钨酸铵含量的增加而减小.随着纺丝液中偏钨酸铵含量的增加,WC/C复合纤维材料的过电势减小,电化学活性面积增大,AMT-1.2的过电势为162 mV,表明WC赋予WC/C复合纤维良好的催化活性.随着复…查看全部>>
Tungsten carbide/carbon(WC/C)composite fibers were prepared by electrospinning method using polyacrylonitrile,N,N-dimethylformamide,and ammonium metatungstate(AMT)as raw materials,whose microstructures and hydrogen evolution activities were analyzed.The results showed that continuous fibers could be obtained with different ammonium metatungstate contents in the spinning solution,whereas the length of WC/C composite fibers after heat treatment was reduced wit…查看全部>>
